Bladder Cancer

Bladder cancer is a cancer that starts in the bladder. The bladder is the body part that holds and releases urine. It is in the center of the lower belly area. These tumors are classified based on the way they grow:
  • Papillary tumors have a wart-like appearance and are attached to a stalk.
  • Nonpapillary tumors are flat. They are much less common. However, they are more invasive and have a worse outcome.
Smoking greatly increases the risk of developing bladder cancer. Up to half of all bladder cancers in men and several in women may be caused by cigarette smoke. Chemical exposure at work. About one in four cases of bladder cancer is caused by coming into contact with to cancer-causing chemicals at work. These chemicals are called carcinogens. Dye workers, rubber workers, aluminum workers, leather workers, truck drivers, and pesticide applicators are at the highest risk. Women who had radiation therapy to treat cervical cancer have an increased risk of developing bladder cancer.

Symptoms of bladder cancer can include:
  • Abdominal pain
  • Blood in the urine
  • Bone pain or tenderness if the cancer spreads to the bone
  • Fatigue
  • Painful urination
  • Urinary frequency
  • Urinary urgency
  • Urine leakage
  • Weight loss

Prostate Cancer

Prostate cancer is cancer that starts in the prostate gland. The prostate is a small, walnut-sized structure that makes up part of a man's reproductive system. It wraps around the urethra, the tube that carries urine out of the body.

The symptoms listed below can occur with prostate cancer, usually at a late stage. These symptoms can also be caused by other prostate problems:
  • Delayed or slowed start of urinary stream
  • Dribbling or leakage of urine, most often after urinating
  • Slow urinary stream
  • Straining when urinating, or not being able to empty out all of the urine
  • Blood in the urine or semen
  • Bone pain or tenderness, most often in the lower back and pelvic bones (only when the cancer has spread)

Breast Cancer

Breast cancer is a cancer that starts in the tissues of the breast. There are two main types of breast cancer:
  • Ductal carcinoma starts in the tubes (ducts) that move milk from the breast to the nipple. Most breast cancers are of this type.
  • Lobular carcinoma starts in the parts of the breast, called lobules, that produce milk.
In rare cases, breast cancer can start in other areas of the breast.
Breast cancer may be invasive or noninvasive. Invasive means it has spread from the milk duct or lobule to other tissues in the breast. Noninvasive means it has not yet invaded other breast tissue. Noninvasive breast cancer is called "in situ."
  • Ductal carcinoma in situ (DCIS), is breast cancer in the lining of the milk ducts that has not yet invaded nearby tissues. It may progress to invasive cancer if untreated.
  • Lobular carcinoma in situ (LCIS) is a marker for an increased risk of invasive cancer in the same or both breasts.
