1. There are two basic types of tumors. One type of tumor is non-cancerous and referred to as benign. The other type is cancerous and referred to as malignant.

Generally speaking, a tumor is caused by body tissues that grow to form an abnormal mass. This abnormal growth is initiated by abnormally regulated or unbalanced cell division. When tumors are benign, they typically grow at a slow rate. Usually, benign tumors are harmless and do not spread to other parts of the body.

Though benign tumors are usually innocuous, their growth can interfere with the ability of healthy tissues to grow and thrive. In fact, they may grow large enough to apply pressure to vital body organs, resulting in serious illness or death. When benign tumors become too large, they may require surgical removal for cosmetic purposes or to preserve surrounding tissues. Once removed, benign tumors usually don't return.

Malignant tumors grow at a faster rate than benign tumors and can cause serious health problems. They may spread to other body tissues and destroy them. These cancerous tumors often cause death.

Treatment of malignant tumors may include surgical removal, radiation, or chemotherapy. Often, there is a direct correlation between the placement of the malignant tumor and the treatment chosen. For example, a tumor confined to a relatively small local area may be removed surgically, while tumors that are more spread out may require radiation treatment or chemotherapy. Sometimes, a combination of surgery, chemotherapy, and radiation is used. Some malignant cancers cannot be cured completely. Often, a tumor that fits this description can still be treated, however, extending the life of the patient.


2. There are two types of bone marrow: red marrow (consisting mainly of myeloid tissue) and yellow marrow (consisting mainly of fat cells). Red blood cells, platelets and most white blood cells arise in red marrow. Both types of bone marrow contain numerous blood vessels and capillaries.
At birth, all bone marrow is red. With age, more and more of it is converted to the yellow type. About half of the bone marrow is red. [1] Red marrow is found mainly in the flat bones, such as the hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") material at the epiphyseal ends of the long bones such as the femur and humerus. Yellow marrow is found in the hollow interior of the middle portion of long bones.
In cases of severe blood loss, the body can convert yellow marrow back to red marrow to increase blood cell production.
