Information for Patients


Also called: Carcinoma, Malignancy, Neoplasms, Tumor

Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, biologic therapy, or stem cell transplantation.

Ear Disorders

Your ear has three main parts: outer, middle and inner. You use all of them in hearing. Sound waves come in through your outer ear. They reach your middle ear, where they make your eardrum vibrate. The vibrations are transmitted through three tiny bones, called ossicles, in your middle ear. The vibrations travel to your inner ear, a snail-shaped organ. The inner ear makes the nerve impulses that are sent to the brain. Your brain recognizes them as sounds. The inner ear also controls balance.

A variety of conditions may affect your hearing or balance:

  • Ear infections are the most common illness in infants and young children.
  • Tinnitus, a roaring in your ears, can be the result of loud noises, medicines or a variety of other causes.
  • Meniere's disease may be the result of fluid problems in your inner ear; its symptoms include tinnitus and dizziness.
  • Ear barotrauma is an injury to your ear because of changes in barometric (air) or water pressure.

Some ear disorders can result in hearing disorders and deafness.

  • Aural polyps
  • Benign ear cyst or tumor
  • Ear discharge
  • Ear emergencies
  • Ear examination
  • Earache
  • Eardrum repair
  • Otosclerosis
  • Ruptured eardrum
