What stage is the serosa layer of rectal cancer?

If you have rectal cancer that reaches the serosa of the rectum, it is usually stage 2 or 3.

The rectal wall can be divided into three layers from the inside to the outside, namely the mucosal layer, the muscular layer and the serosa layer. The staging of rectal cancer is determined according to the degree of infiltration of cancer cells. If the cancer cells only invade the mucosal layer and do not reach the muscular layer and serosa layer, the condition is mild and it is stage 1. If the cancer cells reach all layers of the rectum, namely the muscular layer and serosa layer, but there is no lymph node metastasis, it is stage 2. If lymph node metastasis occurs, it is stage 3. If the lesion is further expanded and invades distant organs, such as the liver, kidneys, brain tissue, muscles, etc., it is stage 4. If rectal cancer invades the serosa layer, it may be stage 2 or stage 3, which mainly depends on whether there is lymph node metastasis.

If you suffer from rectal cancer, you should go to a regular medical institution as soon as possible and take radiotherapy, chemotherapy, surgery and other treatment measures as prescribed by the doctor according to the severity of the lesion and your own weight to try to prolong the patient's life.
