Cancer - prostate
In its early stages, prostate cancer does not cause any symptoms. At a later stage, an adenocarcinoma may lead to:
- pain when urinating
- issues with bladder control
- more frequent urges to urinate at night
- blood in the semen
- painful ejaculation
It's not clear what causes prostate cancer.
Doctors know that prostate cancer begins when some cells in your prostate become abnormal. Mutations in the abnormal cells' DNA cause the cells to grow and divide more rapidly than normal cells do. The abnormal cells continue living, when other cells would die. The accumulating abnormal cells form a tumor that can grow to invade nearby tissue. Some abnormal cells can also break off and spread (metastasize) to other parts of the body.

What Is Adenocarcinoma?
If your doctor tells you that you have adenocarcinoma, it means you have a type of cancer that starts in the glands that line the inside of one of your organs.Adenocarcinoma can happen in many places, like your colon, breasts, esophagus, lungs, pancreas, or prostate.It's natural to feel worried when you find out you have cancer, but remember that treatments can slow or stop the disease. You might need chemotherapy, radiation, targeted therapy, or surgery. You and your doctor will decide on the best approach, based on where your tumors are growing and how long you've had them.
Locations Adenocarcinoma Starts
Your glands make fluids that your body needs to stay moist and work well. You get adenocarcinoma when cells in the glands that line your organs grow out of control. They may spread to other places and harm healthy tissue.Adenocarcinoma can start in the following organs:
Colon and rectum. The colon, which is also called your "large intestine," is part of your digestive system. It's a long tube that helps remove water and nutrients from the food you eat. Adenocarcinoma is the most common type of colon cancer. It starts out as a small polyp, or growth, that's usually harmless at first but can turn into cancer. The disease can also start in your rectum, the part of your large intestine where the leftover waste from digested food, called stool, gets pushed out of your body.
Breasts. Most breast cancers are adenocarcinomas. They start in the glands of the breast where milk is made.
Esophagus. This is the tube that carries food from your mouth to your stomach. Adenocarcinoma usually starts in mucus glands that line the lower part of your esophagus.
Lungs. Adenocarcinoma makes up about 40% of lung cancers. It's most often found in the outer part of the lungs and grows more slowly than other types of lung cancer. You usually get it if you're a smoker or used to be one.
Pancreas. This is an organ in the back of your belly, behind your stomach. It makes hormones and enzymes that help digest food. About 85% of pancreatic cancers are caused by adenocarcinoma. These tumors start in the ducts of this organ.
Prostate. This is a gland in men that's just below the bladder. It helps make some of the fluid that protects sperm cells. Adenocarcinoma starts in the cells that make this fluid. Most prostate cancers are this type.
