A tumor is a collection of abnormal cells grouped together. However, not all tumors are cancerous. A tumor can be benign (not cancerous) or malignant (cancerous). Benign tumors are usually less dangerous and are not able to spread to other parts of the body. Benign tumors can still be dangerous. They can continue to grow and expand locally. This can lead to compression and damage to the surrounding structures. Malignant tumors are usually more serious and can spread to other areas in the body. Continue reading
Bone cancer facts
- The majority of cancer involving the bones is metastatic disease from other remote cancers. Primary bone cancer is much rarer.
- Not all bone tumors are cancerous.
- The most common symptom of bone cancer is pain. The pain is usually mild initially and gradually becomes more intense.
- Treatment of bone cancer includes a combination of surgery, chemotherapy, and radiation therapy.
- Treatment is based on the size and location of the cancer and whether or not the cancer has spread from the bone to surrounding tissues. Continue reading
Radiation therapy is used in a number of cancers as both the main method of killing cancer cells or in combination with surgery (either before or after). The radiation comes in the form of high-energy x-rays that are delivered to the patient only in the areas at highest risk for cancer. These x-rays are similar to those used for diagnostic x-rays, only of a much higher energy. The high-energy of x-rays in radiation therapy results in damage to the DNA of cells, causing tumor cells to die. Continue reading
What are the adrenal glands?
The adrenal glands are small glands that are located just above each kidney (they are sometimes called the suprarenal glands for that reason). The adrenal glands are surrounded by a layer of connective tissue and a layer of fat. They are triangular in shape and consist of several distinct parts: Continue reading
Abdominal cancer is a type of cancer that occurs when there is an uncontrolled growth of abnormal cells anywhere in the abdomen, the area between the lower chest and the groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels. Abdominal cancer is a general term for a variety of cancers. Continue reading
The International Federation of Gynecology and Obstetrics (FIGO) staging systems for vulva, cervix, endometrium, and sarcomas have been revised for the first time in over a decade. The purpose of the staging system is to provide uniform terminology for better communication among health professionals and to provide appropriate prognosis to the patients which results in treatment improvement. This is a constantly evolving process as new therapeutic modalities are developed, new imaging and surgical approaches are applied, and more prognostic information becomes available. The previous system did not reflect the prognosis in some patient subsets where medical research and practice have shown explosive growth of new knowledge in recent years. Continue reading
What is a wound? A wound is type of injury to the skin in which the skin is cut open or had a blunt trauma wherein the wound is inside the skin. It can be an open or a closed wound. In the classification of an open wound, the skin may be abraded, torn, cut or punctured. In the case of a closed wound, wherein the skin is not open because it is caused of a blunt trauma, there could be a contusion or a hematoma or bruising. A hematoma is a sign that there is an internal bleeding which can be mild or hemorrhage. Continue reading
