An abnormal lump in the breast could be a sign of adenocarcinoma, and bloody stool or altered bowel habits could indicate adenocarcinoma in the colon, notes Florida Hospital. Adenocarcinoma is a type of cancer that begins in the glandular cells that line some organs, says the National Cancer Institute.
Adenocarcinoma occurs in different parts of the body, so patients experience different symptoms depending on where the tumor is and whether or not it has spread to other organs, explains Florida Hospital. Sometimes adenocarcinomas do not cause any symptoms, so doctors use tests to screen for them. These procedures include colonoscopies, mammograms, imaging tests, biopsies and blood tests.
The most common organs affected by adenocarcinoma are the lungs, the pancreas, the esophagus, the prostate and the colorectal tract, according to Cancer Treatment Centers of America. Treatment options for adenocarcinomas vary according to where they occur in the body, and may include radiation therapy, surgery and chemotherapy. Radiation is often used in conjunction with surgery and chemotherapy, and modern therapies allow precise targeting of tumors that spares healthy tissue. Surgical removal of cancerous tissue is often used to treat adenocarcinomas, and minimally invasive techniques can be used to reduce the risk of infection and healing time. Chemotherapy uses drugs that kill cancer cells in a specific area or throughout the body.
