Diabetes
By James Pressley
Diabetes
• Diabetes mellitus refers to a group of diseases that affect
how your body uses blood glucose, commonly called blood
sugar. Glucose is vital to your health because it's an
important source of energy for the cells that make up your
muscles and tissues. It's also your brain's main source of
fuel.
Diabetes
• If you have diabetes, no matter what
type, it means you have too much
glucose in your blood, although the
reasons may differ. Too much glucose
can lead to serious health problems.
Aids
Aids
• HIV infection is a condition that can
gradually destroy the immune system, which
makes it harder for the body to fight
infections. When this happens, the person
has aids.
Aids
• Human immunodeficiency virus (HIV) causes HIV
infection and AIDS. The virus attacks the immune
system. As the immune system weakens, the body is
vulnerable to life-threatening infections and cancers.
Once a person has the virus, it stays inside the body
for life.
Cancer
CancerCancer 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. denign
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
• Cancer, also called malignancy, is an abnormal
growth of cells. There are more than 100 types of
cancer, including breast cancer, skin cancer, lung
cancer, colon cancer, prostate cancer, and lymphoma.
Symptoms vary depending on the type. Cancer
treatment may include chemotherapy, radiation,
and/or surgery.
Cancer
• 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.
