Surgery is the mainstay of treatment for clinically localized disease. In feasible cases, a partial cystectomy with "en-bloc" resection of the median umbilical ligament and umbilicus can achieve good results. In progressed stages, radiotherapy seems not to lead to sufficient response rates. However, chemotherapy regimes containing 5-FU (and Cisplatin) have been described to be useful in these cases. In recent years, targeted therapies have been demonstrated to be useful in reports of single cases. These agents included Sunitinib, Gefitinib, Bevacizumab and Cetuximab.

Specific treatment depends on the location, type, and stage of the tumour. Treatment may involve surgery, radiotherapy, or chemotherapy, alone or in combination. This is a specialised area which requires the coordinated expertise of ear, nose and throat (ENT) surgeons (Otorhinolaryngologists) and Oncologists. A severely affected patient may require a laryngectomy, the complete or partial removal of the vocal cords.

Chemotherapy in throat cancer is not generally used to "cure" the cancer as such. Instead, it is used to provide an inhospitable environment for metastases so that they will not establish in other parts of the body. Typical chemotherapy agents are a combination of paclitaxel and carboplatin. Cetuximab is also used in the treatment of throat cancer.

Docetaxel-based chemotherapy has shown a very good response in locally advanced head and neck cancer. Docetaxel is the only taxane approved by US FDA for head and neck cancer, in combination with cisplatin and fluorouracil for the induction treatment of inoperable, locally advanced squamous cell carcinoma of the head and neck.

While not specifically a chemotherapy, amifostine is often administered intravenously by a chemotherapy clinic prior to IMRT radiotherapy sessions. Amifostine protects the gums and salivary glands from the effects of radiation.

Surgical excision (removal) of the tumor is usually recommended if the tumor is small enough, and if surgery is likely to result in a functionally satisfactory result. Radiation therapy with or without chemotherapy is often used in conjunction with surgery, or as the definitive radical treatment, especially if the tumour is inoperable. Surgeries for oral cancers include:

- Maxillectomy (can be done with or without orbital exenteration)

- Mandibulectomy (removal of the mandible or lower jaw or part of it)

- Glossectomy (tongue removal, can be total, hemi or partial). When glossectomy is performed for smaller tumors (< 4 cm), the adequacy of resection (margin status) is best assessed from the resected specimen itself. The status of the margin (positive/tumor cut through versus negative/clear margin) obtained from the glossectomy specimen appears to be of prognostic value, while the status of the margin sampled from the post-glossectomy defect is not. The method of margin sampling appears to correlate with local recurrence: preference for tumor bed/defect margins may be associated with worse local control.

- Radical neck dissection

- Mohs surgery or CCPDMA

- Combinational, e.g. glossectomy and laryngectomy done together

- Feeding tube to sustain nutrition

Owing to the vital nature of the structures in the head and neck area, surgery for larger cancers is technically demanding. Reconstructive surgery may be required to give an acceptable cosmetic and functional result. Bone grafts and surgical flaps such as the radial forearm flap are used to help rebuild the structures removed during excision of the cancer. An oral prosthesis may also be required. Most oral cancer patients depend on a feeding tube for their hydration and nutrition. Some will also get a port for the chemo to be delivered. Many oral cancer patients are disfigured and suffer from many long term after effects. The after effects often include fatigue, speech problems, trouble maintaining weight, thyroid issues, swallowing difficulties, inability to swallow, memory loss, weakness, dizziness, high frequency hearing loss and sinus damage.

Survival rates for oral cancer depend on the precise site and the stage of the cancer at diagnosis. Overall, 2011 data from the SEER database shows that survival is around 57% at five years when all stages of initial diagnosis, all genders, all ethnicities, all age groups, and all treatment modalities are considered. Survival rates for stage 1 cancers are approximately 90%, hence the emphasis on early detection to increase survival outcome for patients. Similar survival rates are reported from other countries such as Germany.

Following treatment, rehabilitation may be necessary to improve movement, chewing, swallowing, and speech. Speech and language pathologists may be involved at this stage.

Chemotherapy is useful in oral cancers when used in combination with other treatment modalities such as radiation therapy. It is not used alone as a monotherapy. When a cure is unlikely, it can also be used to extend life and can be considered palliative but not curative care. Biological agents such as Cetuximab have recently been shown to be effective in the treatment of squamous cell head and neck cancers, and are likely to have an increasing role in the future management of this condition when used in conjunction with other established treatment modalities.

Treatment of oral cancer will usually be by a multidisciplinary team, with treatment professionals from the realms of radiation, surgery, chemotherapy, nutrition, dentistry, and even psychology all possibly involved with diagnosis, treatment, rehabilitation, and patient care.

Radiation therapy is the most common form of treatment. There are different forms of radiation therapy, including 3D conformal radiation therapy, intensity-modulated radiation therapy, particle beam therapy and brachytherapy, which are commonly used in the treatments of cancers of the head and neck. Most people with head and neck cancer who are treated in the United States and Europe are treated with intensity-modulated radiation therapy using high energy photons. At higher doses, head and neck radiation is associated with thyroid dysfunction and pituitary axis dysfunction.

Treatment of hypopharyngeal cancer depends on the prognosis (chance of recovery), age, stage, and general health of the patient. Because hypopharyngeal cancer is often advanced at the time of diagnosis, treatment also depends on the overall goal. The goal may simply be to keep the patient talking, eating, and breathing normally.

Treatment usually begins with surgery and then a course of radiation for cancer that has progressed past Stage I. For cancer that is advanced, which is typical of hypopharyngeal cancer, neoadjuvant chemotherapy may be used. This is performed by administering chemotherapy before surgery. Neoadjuvant chemotherapy in conjunction with radiation and surgery has yielded the best results in patients with Stage III and Stage IV cancers.

There are several treatment options for penile cancer, depending on staging. They include surgery, radiation therapy, chemotherapy, and biological therapy. The most common treatment is one of five types of surgery:

- Wide local excision—the tumor and some surrounding healthy tissue are removed

- Microsurgery—surgery performed with a microscope is used to remove the tumor and as little healthy tissue as possible

- Laser surgery—laser light is used to burn or cut away cancerous cells

- Circumcision—cancerous foreskin is removed

- Amputation (penectomy)—a partial or total removal of the penis, and possibly the associated lymph nodes.

Radiation therapy is usually used adjuvantly with surgery to reduce the risk of recurrence. With earlier stages of penile cancer, a combination of topical chemotherapy and less invasive surgery may be used. More advanced stages of penile cancer usually require a combination of surgery, radiation and chemotherapy.

In addition to all the above, treatment of the underlying disease like brucellosis, is important to limit disease recurrence.

10 to 20% of patients treated for anal cancer will develop distant metastatic disease following treatment. Metastatic or recurrent anal cancer is difficult to treat, and usually requires chemotherapy. Radiation is also employed to palliate specific locations of disease that may be causing symptoms. Chemotherapy commonly used is similar to other squamous cell epithelial neoplasms, such as platinum analogues, anthracyclines such as doxorubicin, and antimetabolites such as 5-FU and capecitabine. JD Hainsworth developed a protocol that includes Taxol and Carboplatinum along with 5-FU. Median survival rates for patients with distant metastases ranges from 8 to 34 months.

Localised disease (carcinoma-in-situ) and the precursor condition, anal intraepithelial neoplasia (anal dysplasia or AIN) can be ablated with minimally invasive methods such as Infrared Photocoagulation.

Previously, anal cancer was treated with surgery, and in early-stage disease (i.e., localised cancer of the anus without metastasis to the inguinal lymph nodes), surgery is often curative. The difficulty with surgery has been the necessity of removing the internal and external anal sphincter, with concomitant fecal incontinence. For this reason, many patients with anal cancer have required permanent colostomies.

Current gold-standard therapy is chemotherapy and radiation treatment to reduce the necessity of debilitating surgery. This "combined modality" approach has led to the increased preservation of an intact anal sphincter, and therefore improved quality of life after definitive treatment. Survival and cure rates are excellent, and many patients are left with a functional sphincter. Some patients have fecal incontinence after combined chemotherapy and radiation. Biopsies to document disease regression after chemotherapy and radiation were commonly advised, but are not as frequent any longer. Current chemotherapy consists of continuous infusion 5-FU over four days with bolus mitomycin given concurrently with radiation. 5-FU and cisplatin are recommended for metastatic anal cancer.

In the treatment of Kangri cancer, surgery is, most often, the first-line course of action to remove the primary tumor.

Several drugs that target molecular pathways in lung cancer are available, especially for the treatment of advanced disease. Erlotinib, gefitinib and afatinib inhibit tyrosine kinase at the epidermal growth factor receptor. Denosumab is a monoclonal antibody directed against receptor activator of nuclear factor kappa-B ligand. It may be useful in the treatment of bone metastases.

External beam radiotherapy has been used in one person to prevent the relapse and growth of tumor metastases to the head and neck regions. The prophylactic applications of radiation have been noted as “encouraging” in this one case, reducing some tumors and eliminating others.

Another study with a couple of the same authors found that radiotherapy after surgery helped with the reduction and cure of head and neck tumors in additional cases. The researchers suggest that external beam radiotherapy should be part of the treatment course for patients who have or at risk of developing tumors in the head and neck areas.

Several treatments can be administered via bronchoscopy for the management of airway obstruction or bleeding. If an airway becomes obstructed by cancer growth, options include rigid bronchoscopy, balloon bronchoplasty, stenting, and microdebridement. Laser photosection involves the delivery of laser light inside the airway via a bronchoscope to remove the obstructing tumor.

Staging and treatment are generally handled by an oncologist familiar with gynecologic cancer. Surgery is a mainstay of therapy depending on anatomical staging and is usually reserved for cancers that have not spread beyond the vulva. Surgery may involve a wide local excision, radical partial vulvectomy, or radical complete vulvectomy with removal of vulvar tissue, inguinal and femoral lymph nodes. In cases of early vulvar cancer, the surgery may be less extensive and consist of wide excision or a simple vulvectomy. Surgery is significantly more extensive when the cancer has spread to nearby organs such as the urethra, vagina, or rectum. Complications of surgery include wound infection, sexual dysfunction, edema and thrombosis, as well as lymphedema secondary to dissected lymph nodes.

Sentinel lymph node (SLN) dissection is the identification of the main lymph node(s) draining the tumor, with the aim of removing as few nodes as possible, decreasing the risk of adverse effects. Location of the sentinel node(s) may require the use of technetium(99m)-labeled nano-colloid, or a combination of technetium and 1% isosulfan blue dye, wherein the combination may reduce the number of women with "'missed"' groin node metastases compared with technetium only.

Radiation therapy may be used in more advanced vulvar cancer cases when disease has spread to the lymph nodes and/or pelvis. It may be performed before or after surgery. Chemotherapy is not usually used as primary treatment but may be used in advanced cases with spread to the bones, liver or lungs. It may also be given at a lower dose together with radiation therapy.

Women with vulvar cancer should have routine follow-up and exams with their oncologist, often every 3 months for the first 2–3 years after treatment. They should not have routine surveillance imaging to monitor the cancer unless new symptoms appear or tumor markers begin rising. Imaging without these indications is discouraged because it is unlikely to detect a recurrence or improve survival and is associated with its own side effects and financial costs.

Surgery is the most common treatment for cancer of the urethra. One of the following types of surgery may be done: Open excision, Electro-resection with flash, Laser surgery, Cystourethrectomy, Cystoprostatectomy, Anterior body cavity, or Incomplete or basic penectomy surgery.

Chemotherapy is sometimes used to destroy urethral cancer cells. It is a systemic urethral cancer treatment (i.e., destroys urethral cancer cells throughout the body) that is administered orally or intravenously. Medications are often used in combination to destroy urethral cancer that has metastasized. Commonly used drugs include cisplatin, vincristine, and methotrexate.

Side effects include anemia (causing fatigue, weakness), nausea and vomiting, loss of appetite, hair loss, mouth sores, increased risk for infection, shortness of breath, or excessive bleeding and bruising.

Treatment of invasive carcinoma of no special type (NST) depends on the size of the mass (size of the tumor measured in its longest direction):

- <4 cm mass: surgery to remove the main tumor mass and to sample the lymph nodes in the axilla. The stage of the tumor is ascertained after this first surgery. Adjuvant therapy (i.e., treatment after surgery) may include a combination of chemotherapy, radiotherapy, hormonal therapy (e.g., tamoxifen) and/or targeted therapy (e.g., trastuzumab). More surgery is occasionally needed to complete the removal of the initial tumor or to remove recurrences.

- 4 cm or larger mass: modified (a less aggressive form of radical mastectomy) radical mastectomy (because any malignant mass in excess of 4 cm in size exceeds the criteria for a lumpectomy) along with sampling of the lymph nodes in the axilla.

The treatment options offered to an individual patient are determined by the form, stage and location of the cancer, and also by the age, history of prior disease and general health of the patient. Not all patients are treated the same way.

Treatment methods include surgery, chemotherapy, radiation therapy and medication.

Identifying and treatment the underlying malignancy constitutes an uptime approach. Topical 5-fluorouracil may occasionally be help, as may oral retinoids, topical steroids, vitamin A acid, urea, salicylic acid, podophyllotoxin, and cryodestruction employing liquid.

The US Preventive Services Task Force (USPSTF) in 2013 stated evidence was insufficient to determine the balance of benefits and harms of screening for oral cancer in adults without symptoms by primary care providers. The American Academy of Family Physicians comes to similar conclusions while the American Cancer Society recommends that adults over 20 years who have periodic health examinations should have the oral cavity examined for cancer. The American Dental Association recommends that providers remain alert for signs of cancer during routine examinations.

There are a variety of screening devices, however, there is no evidence that routine use of these devices in general dental practice is helpful. However, there are compelling reasons to be concerned about the risk of harm this device may cause if routinely used in general practice. Such harms include false positives, unnecessary surgical biopsies and a financial burden on the patient.

Treatment is dependent on type of cancer, location of the cancer, age of the person, and whether the cancer is primary or a recurrence. Treatment is also determined by the specific type of cancer. For a small basal-cell cancer in a young person, the treatment with the best cure rate (Mohs surgery or CCPDMA) might be indicated. In the case of an elderly frail man with multiple complicating medical problems, a difficult to excise basal-cell cancer of the nose might warrant radiation therapy (slightly lower cure rate) or no treatment at all. Topical chemotherapy might be indicated for large superficial basal-cell carcinoma for good cosmetic outcome, whereas it might be inadequate for invasive nodular basal-cell carcinoma or invasive squamous-cell carcinoma.. In general, melanoma is poorly responsive to radiation or chemotherapy.

For low-risk disease, radiation therapy (external beam radiotherapy or brachytherapy), topical chemotherapy (imiquimod or 5-fluorouracil) and cryotherapy (freezing the cancer off) can provide adequate control of the disease; all of them, however, may have lower overall cure rates than certain type of surgery. Other modalities of treatment such as photodynamic therapy, topical chemotherapy, electrodesiccation and curettage can be found in the discussions of basal-cell carcinoma and squamous-cell carcinoma.

Mohs' micrographic surgery (Mohs surgery) is a technique used to remove the cancer with the least amount of surrounding tissue and the edges are checked immediately to see if tumor is found. This provides the opportunity to remove the least amount of tissue and provide the best cosmetically favorable results. This is especially important for areas where excess skin is limited, such as the face. Cure rates are equivalent to wide excision. Special training is required to perform this technique. An alternative method is CCPDMA and can be performed by a pathologist not familiar with Mohs surgery.

In the case of disease that has spread (metastasized), further surgical procedures or chemotherapy may be required.

Treatments for metastatic melanoma include biologic immunotherapy agents ipilimumab, pembrolizumab, and nivolumab; BRAF inhibitors, such as vemurafenib and dabrafenib; and a MEK inhibitor trametinib.

Historically, the combination of external-beam radiation therapy (EBRT) has been the most common treatment for vaginal cancer. In early stages of vaginal cancer, surgery also has some benefit. This management and treatment is less effective for those with advanced stages of cancer but works well in early stages with high rates of cure. Advanced vaginal cancer only has a 5-year survival rates of 52.2%, 42.5% and 20.5% for patients with stage II, III and IVa disease. Newer treatments for advanced stages of ovarian have been developed. These utilize concurrent carboplatin plus paclitaxel, EBRT and high-dose-rate interstitial brachytherapy (HDR-ISBT).

When the chance of surgical removal of all cancerous tissue is very low or when the surgery has a chance of damaging the bladder, vagina or bowel, radiation therapy is used. When a tumor is less than 4 cm in diameter, radiation therapy provides excellent results. In these instances, the 5-year survival rate is greater than 80%. Treatments are individualized due to the rarity of vaginal cancer studies.

Superficial tumors (those not entering the muscle layer) can be "shaved off" using an electrocautery device attached to a cystoscope, which in that case is called a resectoscope. The procedure is called transurethral resection of bladder tumor—TURBT—and serves primarily for pathological staging. In case of non-muscle invasive bladder cancer the TURBT is in itself the treatment, but in case of muscle invasive cancer, the procedure is insufficient for final treatment.

Immunotherapy by intravesicular delivery of Bacillus Calmette–Guérin (BCG) is also used to treat and prevent the recurrence of superficial tumors. BCG is a vaccine against tuberculosis that is prepared from attenuated (weakened) live bovine tuberculosis bacillus, Mycobacterium bovis, that has lost its virulence in humans. BCG immunotherapy is effective in up to 2/3 of the cases at this stage, and in randomized trials has been shown to be superior to standard chemotherapy. The mechanism by which BCG prevents recurrence is unknown, but the presence of bacteria in the bladder may trigger a localized immune reaction which clears residual cancer cells.

Patients whose tumors recurred after treatment with BCG are more difficult to treat. Many physicians recommend cystectomy for these patients. This recommendation is in accordance with the official guidelines of the European Association of Urologists (EAU) and the American Urological Association (AUA) However, many patients refuse to undergo this life changing operation, and prefer to try novel conservative treatment options before opting to this last radical resort. Device assisted chemotherapy is one such group of novel technologies used to treat superficial bladder cancer. These technologies use different mechanisms to facilitate the absorption and action of a chemotherapy drug instilled directly into the bladder. Another technology - electromotive drug administration (EMDA) – uses an electric current to enhance drug absorption after surgical removal of the tumor. Another technology, thermotherapy, uses radio-frequency energy to directly heat the bladder wall, which together with chemotherapy shows a synergistic effect, enhancing each other's capacity to kill tumor cells. This technology was studied by different investigators.

Improvement usually parallels that of the cancer, whether surgical or chemotherapeutic. Generalization of the associated visceral malignancy may worsen the eruption.

The initial approach to tubal cancer is generally surgical and similar to that of ovarian cancer. As the lesion will spread first to the adjacent uterus and ovary, a total abdominal hysterectomy is an essential part of this approach and removes the ovaries, the tubes, and the uterus with the cervix. Also, peritoneal washings are taken, the omentum is removed, and pelvic and paraaortic lymph nodes are sampled. Staging at the time of surgery and pathological findings will determine further steps. In advanced cases when the cancer has spread to other organs and cannot be completely removed cytoreductive surgery is used to lessen the tumor burden for subsequent treatments. Surgical treatments are typically followed by adjuvant usually platinum-based chemotherapy.

Also radiation therapy has been applied with some success to patients with tubal cancer for palliative or curative indications

Treatment options vary and depend on the type and stage of cancer. Common treatments include surgery, chemotherapy, radiation therapy, amputation, and immunotherapy. A combination of therapies may be used. Knowledge and treatment of cancer have increased significantly in the past three decades. Survival rates have also increased due to the increase prevalence of canine cancer treatment centers and breakthroughs in targeted drug development. Canine cancer treatment has become an accepted clinical practice and access to treatment for owners has widely expanded recently. Cancer-targeting drugs most commonly function to inhibit excessive cell proliferation by attacking the replicating cells. However, there is still a prevalent pharmacy gap in veterinary oncology.

There is one canine tumor vaccine approved by the USDA, for preventing canine melanoma. The Oncept vaccine activates T-cell responses and antibodies against tumor-specific tyrosinase proteins. There is limited information about canine tumor antigens, which is the reason for the lack of tumor-specific vaccines and immunotherapy treatment plans for dogs.

Success of treatment depends on the form and extent of the cancer and the aggressiveness of the therapy. Early detection offers the best chance for successful treatment. The heterogeneity of tumors makes drug development increasingly complex, especially as new causes are discovered. No cure for cancer in canines exist.

Some dog owners opt for no treatment of the cancer at all, in which case palliative care, including pain relief, may be offered. Regardless of how treatment proceeds following a diagnosis, the quality of life of the pet is an important consideration. In cases where the cancer is not curable, there are still many things which can be done to alleviate the dog's pain. Good nutrition and care from the dog's owner can greatly enhance quality of life.
