The average age at time of EIN diagnosis is approximately 52 years, compared to approximately 61 years for carcinoma. The timeframe and likelihood of EIN progression to cancer, however, is not constant amongst all women. Some cases of EIN are first detected as residual premalignant disease in women who already have carcinoma, whereas other EIN lesions disappear entirely and never lead to cancer. For this reason, treatment benefits and risks must be individualized for each patient under the guidance of an experienced physician.

Risk factors for development of EIN and the endometrioid type of endometrial carcinoma include exposure to estrogens without opposing progestins, obesity, diabetes, and rare hereditary conditions such as hereditary nonpolyposis colorectal cancer. Protective factors include use of combined oral contraceptive pills (low dose estrogen and progestin), and prior use of a contraceptive intrauterine device.

Endometrial intraepithelial neoplasia (EIN) is a premalignant lesion of the uterine lining that predisposes to endometrioid endometrial adenocarcinoma. It is composed of a collection of abnormal endometrial cells, arising from the glands that line the uterus, which have a tendency over time to progress to the most common form of uterine cancer—endometrial adenocarcinoma, endometrioid type.

Crucial in the decision to breed would be the primary cause of FCKS in the litter, which may or may not be genetic. Some recovered FCKS adults have produced FCKS offspring in their turn (or lines that consistently produce flat kittens), and breeding from them is therefore inadvisable. However, repeat matings in which FCKS has appeared does not always result in further FCKS kittens. Queens and studs who consistently throw complete litters of kittens with the condition are generally neutered since a genetically linked cause for the condition can be introduced into lines that do not produce it by breeding with lines in which it is common. Isolated instances of single flat kittens in an otherwise healthy litter are unlikely to have a genetic component in the condition, and neutering of parents of such kittens is not usually necessary in pedigree breeding, especially since this may have detrimental effects on the gene pool.

If the cause of flattening is colic related to over-production of milk then this would not be cause for neutering. The only way to determine if the cause is digestive would be if the condition was alleviated in all cases by pinching the phrenic nerve and/or use of liquid paraffin to relieve colic resulting in improvement in the condition.

Line-breeding or inbreeding is highly inadvisable in lines where FCKS has appeared, and the practice may cause the condition to appear in lines where it has not previously been recorded.

Splinting the kitten in a specially-constructed corset encourages the ribcage to a more normal position, and reported mortality seemed to decline when this practice was introduced. This may be because encouraging the chest to a more correct position helps the lungs to re-inflate. However a large proportion of kittens cannot tolerate a splint, and the distress it causes is extremely counterproductive. It can also be dangerous in cases where pressure on the sides causes the sternum to move inwards rather than outwards, and should only be undertaken with veterinary support and advice. Some kittens recover without intervention, so it is not known whether the various treatments based on encouraging the thorax to return to a normal shape contributed to recovery.

Some breeders have found that putting pressure on the sides of the ribcage can help, as the chest rounds out with encouragement (gentle pressure timed to coincide with the natural movement of the thorax in breathing), but usually the chest goes flat again as soon as massage is discontinued. It may however help in encouraging the lungs to inflate a little more with each breath, but should not be used if it causes distress to the kitten. Many breeders report that affected kittens seem to enjoy massage. Encouraging a kitten to lie on its side can be helpful, and draping another kitten (or the mother's arm) over it while it is sleeping places a gentle continuous pressure on the ribcage which may also be helpful. If the kitten is uncomfortable it will move away. (It is important to ensure that pressure is not placed on the kitten if it is lying flat on its chest.)

Over-handling FCKS kittens can lead to unnecessary weight loss and lethargy, so the use of massage, waking the kitten for extra feeds from the mother etc. should be checked against gains and losses in weight. Some vets believe that encouraging the kitten to cry and also to have to move more to reach its mother may be helpful. There is little or no data from breeders supporting this theory.

Schwabenhass (German for "hatred against Swabians") is a political slogan about aversion to the approximately 300,000 strong Swabian minority in Berlin. In 2013, the so-called "spätzlestreit" gained nationwide attention.

"Schwabenhass" occurs in different ethnic groups in Germany. Already neighboring Badener prefer their distance according to the notion, "we have nothing against Swabians, at least nothing with sustainable remedy effect". Theodor Fontane had Effi Briest say, that already in the 19th century, Swabian neighbors were a reason to start leaving certain neighborhoods in Berlin.

The term Schwob/ Szwab has been used by Poles and Swiss as ethnic slur for all Germans.

Similar prejudices applied to the Donauschwaben in Hungary despising everything German.
