summary

Four years after operation, my father's bowel movement was not smooth recently. It's hard to fall all day. But the stool is normal. After 2 days of treatment, I feel obviously improved. Let me share with you the difference between lower anal canal cancer and rectal cancer. It's my experience.

What is the difference between anal cancer and rectal cancer

Symptom 1: if rectal cancer infiltrates other organs and tissues, it can cause symptoms of lesions, invade the bladder and prostate, and cause cystitis, urethritis, vesicorectal fistula and urethrorectal fistula.

Symptom 2: intestinal stricture and obstruction. The tumor infiltrates around the circumference of the intestinal wall, making the intestinal cavity narrow. Especially at the junction of rectum and sigmoid colon, it is mostly narrow type of hard cancer, which is easy to cause obstruction. Rectal carcinoma of the ampulla is usually ulcerative. It is estimated that it takes about one to two years to cause obstruction, narrowing of stool, difficulty in defecation, constipation, abdominal discomfort, bloating and pain. Due to the accumulation of feces, a cord like mass can be found in the upper part of the obstruction, sometimes in the left lower abdomen.

Symptom 3: hematochezia is the most common symptom of rectal cancer, but it is often ignored by patients or misdiagnosed as hemorrhoids and delayed treatment, making the condition worse. Hematochezia is mostly red or dark red, mixed with mucus bloody stool, or pus bloody stool, sometimes accompanied by blood clots and necrotic tissue. The above symptoms are the result of blood supply disturbance, tissue necrosis, erosion, ulceration, infection and ulcer formation after cancer proliferation.

matters needing attention

In the selection of multiple targeted drugs for treatment, it should be noted that the target of the two targeted drugs is different, because the current clinical research data show that when the targeted drugs are added to the treatment, the efficacy does not increase, and the survival time of patients after drug treatment does not extend.
