Adenocarcinoma cells are cancer cells that originate from glandular cells lining the internal or external surfaces of the body, including organs such as the lungs, breast, colon, prostate, pancreas, and stomach. These cells are characterized by their ability to form gland-like structures and produce mucus.

Adenocarcinomas are among the most common types of cancer, accounting for approximately 40% of all cancer cases. The cells are known for their ability to invade surrounding tissues and spread to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis.

Symptoms of adenocarcinoma can vary depending on the location of the tumor, but can include weight loss, fatigue, and pain. Treatment options for adenocarcinoma typically depend on the stage and location of the tumor and can include surgery, radiation therapy, chemotherapy, or targeted therapy.

Research on adenocarcinoma cells is important for understanding the biology of the disease and developing new treatments. In vitro studies using adenocarcinoma cells are often used to investigate the mechanisms underlying tumor growth and metastasis and to test the effectiveness of new drugs or therapies.
