What's wrong with black stools caused by rectal cancer?

What happens if rectal cancer causes black stools?

The black spots on rectal cancer are caused by tumor ulcers, adverse reactions to chemotherapy, and tumor liver metastasis. The details are as follows:

1. Tumor rupture

Rectal cancer is a malignant disease. The tumor has a rich blood supply and a fragile texture. When the tumor is rubbed by feces, it will bleed. When a small amount of blood combines with intestinal sulfide, black stool will appear.

2. Adverse reactions to chemotherapy

Some patients with rectal cancer need to receive chemotherapy, which can cause bone marrow suppression, leading to a decrease in the number of platelets in the peripheral blood, spontaneous bleeding tendency in the body, and black stools.

3. Liver metastasis

Cancer cells have the characteristics of unlimited proliferation and easy metastasis. The liver has a rich blood supply. Cancer cells of advanced rectal cancer can easily metastasize to the liver, leading to a decrease in the liver's ability to synthesize coagulation factors. Coagulation dysfunction in the body can cause gastrointestinal bleeding and black stools.

Patients with rectal cancer should pay attention to black stools, seek medical attention in time, evaluate the condition, and take intervention measures under the guidance of a doctor. Maintain a balanced diet and nutrition every day, and avoid eating rough, hard, and indigestible foods. For patients with early rectal cancer, if they can be discovered and treated in a standardized manner in time, the vast majority of patients have a good prognosis. Patients with mid- and late-stage rectal cancer should also build confidence in treatment, actively cooperate with doctors for treatment, and improve their quality of life.
