What is adenocarcinoma?
What can cause adenocarcinoma?
Though the exact cause of adenocarcinoma is not fully understood, researchers have identified a variety of risk factors that are associated with this type of cancer:
- Family history of cancer (twins, siblings, first-degree relatives)
- Environmental toxins
- Secondhand smoke
- Radon exposure
- Asbestos exposure
- Silica exposure
- Diesel exhaust
- Exposure to air pollution and other chemicals
- Prior radiation exposure
- Beta carotene supplements
Smoking is the most common risk factor associated with all types of cancers. It is important to note that these risk factors will not necessarily lead to lung cancer. Similarly, an individual may develop lung cancer without having any of these risk factors.
Is adenocarcinoma an aggressive cancer?
Adenocarcinoma happens when cells in the glands that line organs grow out of control. They may spread to other places and harm healthy organs. Adenocarcinoma in different organs manifests differently.
Adenocarcinoma can start in:
- Colon and rectum
- Most breast cancers are adenocarcinomas.
- They start in the glands of the breast where milk is produced.
- Adenocarcinoma usually starts in glands that line the lower part of your esophagus (food pipe).
- 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.
- This is an organ in the abdomen that secretes hormones and chemicals which help in food digestion.
- About 85% of pancreatic cancers are adenocarcinoma.
- This is a gland in men situated below the urine bladder.
- Prostate gland cancers are mostly adenocarcinomas.
How is adenocarcinoma diagnosed?
Initially, an individual does not experience any symptoms. Adenocarcinoma is usually diagnosed in late stages, and it already spreads by the time symptoms are obvious. Symptoms may include pain, weight loss swelling, diarrhea, bleeding and weakness. Below are few common tests to confirm adenocarcinoma:
- Colonoscopy checks intestines for masses which might be adenocarcinomas (polyps).
- Blood tests check for anemia (blood loss) as it is an important indication for possible cancer.
- Imaging tests (CT, MRI) are helpful to see if any of the tissues in organs appear abnormal. Imaging tests also help the doctor monitor a cancer treatment’s effectiveness.
How is adenocarcinoma treated?
Treatment of adenocarcinoma depends on the anatomical site and its manifestations. Below are treatment options for adenocarcinoma.
- Surgery: The primary treatment after diagnosis is usually to remove the tumor and the tissue around it. Usually, the tissue is sent to pathology lab to determine the aggressiveness of the cancer. Depending on the pathology result, an individual might need to combine other treatments with surgery.
- Chemotherapy: Drugs used in chemotherapy can kill adenocarcinoma cells, slow their growth, or even cure the disease.
- Radiation: Generally, high-energy X-rays or other types of rays are exposed to the cancerous site to kill the cancer cells.
Cancer treatment can have side effects which include vomiting and weakness; doctors usually treat these side effects with medications.

Breast cancer is an invasive tumor that develops in the mammary gland. Breast cancer is detected via mammograms, breast self-examination (BSE), biopsy, and specialized testing on breast cancer tissue. Treatment of breast cancer may involve surgery, radiation, hormone therapy, chemotherapy, and targeted therapy. Breast cancer risk may be lowered by managing controllable risk factors.
What you should know about breast cancer
- Breast cancer is the most common cancer among American women.
- One in every eight women in the United States develops breast cancer.
- There are many types of breast cancer that differ in their capability of spreading (metastasize) to other body tissues.
- The causes of breast cancer are unknown, although medical professionals have identified a number of risk factors.
- There are 11 common types of breast cancer and 4 uncommon types of breast cancer.
- Breast cancer early signs and symptoms include
- a lump in the breast or armpit,
- bloody nipple discharge,
- inverted nipple,
- orange-peel texture or dimpling of the breast's skin (peau d'orange),
- breast pain or sore nipple,
- swollen lymph nodes in the neck or armpit, and
- a change in the size or shape of the breast or nipple.
- Breast cancer can also be symptom free, which makes following national screening recommendations an important practice.
- Breast cancer is diagnosed during a physical exam, by a self-exam of the breasts, mammography, ultrasound testing, and biopsy.
- Treatment of breast cancer depends on the type of cancer and its stage (0-IV) and may involve surgery, radiation, or chemotherapy.

Breast Cancer Follow-Up Self-ExamA breast cancer follow-up self-exam is a test that may help a woman detect a recurrence of the disease. A woman should perform a monthly self-exam of both breasts as well as attend scheduled follow-up appointments to detect any breast cancer recurrence early. Lymph node involvement, tumor size, hormone receptor status, histologic grade, nuclear grade, and oncogene expression help determine the likelihood of a recurrence.
Where Breast Cancer SpreadsWhen breast cancer spreads, or metastasizes, it often goes to these five places: the lymph nodes, bones, liver, lungs, and brain. See how breast cancer metastasis affects the body, possible symptoms, and treatment.

CancerCancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.

Gastroesophageal Junction AdenocarcinomaGastroesophageal junction adenocarcinoma is cancer that forms in the area where the esophagus joins the stomach. Having GERD and Barrett's esophagus increases one's odds of developing gastroesophageal junction adenocarcinoma. Symptoms and signs of GE junction adenocarcinoma include dysphagia, weight loss, black stool, cough, nausea, and vomiting. Treatment may include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy.
Genetic Testing for Breast CancerIntensive genetic counseling is required before undergoing genetic tests for breast cancer. During this educational counseling session, the health care provider can fully explain the benefits and risks of genetic testing and answer any questions you may have. You will also be required to sign a consent form prior to participating in any genetic tests. The form is an agreement between you and your doctor, showing that you have discussed the test and how its results might affect your family.
Pancreatic CancerPancreatic cancer is a malignant tumor of the pancreas. Pancreatic cancer has been called a "silent" disease because early pancreatic cancer usually does not cause early symptoms. Typically, pancreatic cancer has metastasized (spread to adjacent organs, such as the liver) by the time most people receive a dignosis of pancreatic cancer. Symptoms and signs usually appear later in the course of the disease and include jaundice, back pain, nausea, weight loss, itching, and loss of appetite. Treatment depends upon the type of pancreatic cancer but may include surgery, chemotherapy, and/or radiation therapy.
Prostate cancer is the most common cancer in men after skin cancer.
- Risk factors include age, family history, ethnicity, and diet.
- Prostate cancer is diagnosed by a digital rectal exam, prostate-specific antigen (PSA) test, and prostate biopsy.
- Symptoms may include
- frequent need to urinate,
- incontinence, pain,
- blood in the urine,
- fatigue, and more.
- Prognosis and treatment depend on cancer staging.
- Watchful waiting,
- cryotherapy, and
- other management strategies are available.
- Research and clinical trials strive to find new and better treatments for prostate cancer.
Prostate Cancer Facts
Prostate cancer is a leading cause of cancer and cancer death in males; in some men, identifying it early may prevent or delay metastasis and death from prostate cancer.
- The prostate is a walnut-shaped gland that is a part of the male reproductive system that wraps around the male urethra at it exits the bladder.
- Prostate cancer is common in men over 50 years of age, with the risk of developing prostate cancer increases with aging.
Prostate Cancer Staging and Survival Rates
The prognosis for prostate cancer, as with any cancer, depends on how advanced the cancer has become, according to established stage designations. The patient's PSA score at diagnosis, as well as their Gleason score (the grading system used to determine the aggressiveness of prostate cancer) determines the prognosis and final stage designation. Prostate cancer has a high survival rate in general, but your chances depend on the stage of the cancer.
