Halsted radical mastectomy
:
Seee mastectomy.
hematologist
(hem-uh-tahl-o-jist)
:
a doctor who specializes in diseases of the blood and blood-forming tissues.
hematoma
(hem-uh-to-ma)
:
a collection of blood outside a blood vessel caused by a leak or injury. Hematomas that occur in the breast after injury or after surgery may feel like a lump. As with other breast lumps, it's important to have it checked to be sure that it is indeed a hematoma and not a more serious problem.
hemoccult (Guaiac test)
:
other names for a fecal occult blood test.
HER2
:
one of the oncogenes that may become "turned on" (activated), Activation can cause normal cells to change into cancer cells and can cause some cancer cells to grow and spread especially fast. See also oncogene.
HER2/neu gene
:
this oncoprotein is present in very small amounts on the outer surface of normal breast cells. About 25% - 30% of breast cancers have too much of this protein. HER stimulates cell growth, and breast cancers that produce too much of this protein tend to be more aggressive. A monoclonal antibody that attaches to the HER2 protein slows the growth of breast cancer cells and may also stimulate the immune system to more effectively attack the cancer. Some other types of cancer also have too much HER2/neu protein. Studies of monoclonal antibody therapy for these cancers are in progress.
hereditary cancer syndrome
:
conditions associated with cancers that occur in multiple family members because of an inherited, mutated gene.
hereditary nonpolyposis colon cancer (HNPCC)
:
people with this condition tend to develop cancer at a young age without first having many polyps.
hesitancy
:
inability to start the stream of urine promptly.
high risk
:
when the chance of developing cancer is greater than that normally seen in the general population. People may be at high risk from many factors, including heredity (such as a family history of breast cancer), personal habits (such as smoking), or the environment (such as overexposure to strong sunlight).
