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.
How 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 your:
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.
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.
How Is It Diagnosed?
Your doctor will give you a physical exam. He may feel your organs to see if there is any swelling or a growth.
He may also notice something's not right when you have regular screening tests like a colonoscopy, when a doctor puts a tube into your colon to check for polyps.
You may also get tests to see if you have adenocarcinoma in any of your organs:
Blood tests. Your blood may show signs of possible cancer. For example, your doctor may check it to see if you have anemia from a bleeding tumor. Also, high levels of some enzymes or other things made by cancer cells might mean canceer is likely.
Imaging tests. They can help see if any of the tissues in your organs don't look normal. You may get a CT scan, which is a powerful X-ray that makes detailed pictures inside your body. Or you might need an MRI, which uses powerful magnets and radio waves to make pictures of organs and tissues.
If you do have cancer and start treatment, imaging tests can also help your doctor learn how well your treatment is working.
Biopsy. Your doctor takes a small sample of tissue from the organ where he thinks you may have cancer. For example, he may remove a polyp or growth from your colon, or use a small needle to remove tissue from your breast.
A doctor called a pathologist will look at it under a microscope to see if there are cancer cells. A biopsy can also show if they are just in that one organ, have spread from another place in your body, or how much they've grown.
How Is It Treated?
Your treatment depends on the type of adenocarcinoma you have and how far along your disease has moved. This is called the stage of your cancer.
Surgery. Your first treatment will probably be to remove the tumor and tissue around it. Your doctor can then look at the tissue to see if you're cured or if there still may be cancer cells in your body. You may need to combine other treatments with surgery to make sure your cancer is gone.
Chemotherapy. Drugs can kill adenocarcinoma cells, slow their growth, or even cure your disease.
Radiation. Doctors use high-energy X-rays or other types of rays to kill your cancer cells.
You may need chemo along with surgery and radiation to treat your cancer. Some chemo drugs may kill both cancer and healthy cells. Other, newer drugs may target just your cancer cells.
Your cancer treatment can have side effects. You might get very tired or feel like you need to throw up. Your doctor can suggest ways to manage these problems. He may prescribe drugs that fight nausea.
Talk to your family and friends about how you're feeling, and don't hesitate to ask them for help while you're getting treatment. Also tell them about your worries and fears. They can be a huge source of support.
