Leukemia is a type of cancer that affects the blood cells and the bone marrow. This cancer usually begins in the bone marrow and undergoes a leukemic change which means, the cell might grow and survive better than normal cells. As a result, the cells suppress the growth and development of normal cells which might disrupt bodily functions and cause life-threatening symptoms.

Psoriasis is a chronic skin disease that speeds up the natural life cycle of skin cells. The condition causes healthy skin cells to multiply rapidly and grow over the existing skin thus creating red patches on the skin. There are no known causes of psoriasis; however, studies indicate that an imbalance in neutrophils (white blood cells) to aid the immune system fight off infections can trigger an overproduction of skin cells leading to psoriasis.

The human body does its best to protect itself from ailments and injuries; the immune system takes care of the diseases, whereas, blood loss due to injuries are taken care of by blood clotting or the process of coagulation. Blood clotting might not appear to be quite significant, but it prevents excessive bleeding when you rupture a blood vessel.

Leukemia is the cancer of the blood that occurs when there is an abnormal growth of some blood cells in the bone marrow. This fast abnormal growth of any one type of blood cell then prevents the healthy growth of other blood cells, which then becomes a cancer of the blood.

Chronic obstructive pulmonary disease or COPD is a condition that afflicts the normal functioning of the lungs. The disease is characterized by the inflammation of the lungs, thereby causing an obstruction in the flow of air through the organs. The term is used to collectively denote several diseases related to the lungs, including refractory asthma, emphysema, and chronic bronchitis.

The lymphatic system is the body’s defense system against infections. This system includes the spleen, bone marrow, thymus gland, and the lymph nodes. When the white blood cells in the lymphatic system start to reproduce at a faster rate, lymphoma occurs. It is a form of cancer that affects all the organs of the lymphatic system as well as the other parts of the body.
