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.
