Normal cells grow, divide and die all according to an intracellular program and in response to external signals. When cells transform into cancerous cells, they divide uncontrollably, do not die when they should, damage the surrounding normal...
Merck Manuals, an online medical library, reports that 213,000 women were diagnosed with breast cancer in the United States in 2006. Breast cancer is the second most common type of cancer, and the second leading cause of death due to cancer. There...
According to the National Cancer Institute, each year more than 192,000 women are diagnosed with breast cancer. Merck Manuals, an online medical library, reports that breast cancer is the second-most common type of cancer and the second-most...
In 2009, the American Cancer Society estimated that 192,370 new cases of breast cancer would be diagnosed in the year. A number of pathological factors, including tumor size, the spreading of the tumor and how quickly the tumor is growing, help...
The bladder is the organ in your body that stores urine, and bladder cancer develops in the tissues of this muscular organ. The American Cancer Society estimates that men have a one in 26 lifetime risk of developing bladder cancer, while women...
Brain tumors vary widely and the symptoms exhibited by patients with brain cancer may be quite different depending on the patient and the tumor's characteristics. Different grades of tumor, the locations involved and other affected areas in and...
A brain tumor is a group of malignant cells that are abnormally dividing and are not able to be controlled. Brain tumors are classified by the kind of cell from which they arise and their behavior pattern, and some are graded on how malignant or...
Breast cancer develops from normal cells within the breast that undergo genetic changes that cause them to become tumorigenic. A number of these changes are detectable by monitoring specific protein markers that are found specifically in breast...
Cancers of the brain and nervous system are rare but very serious as they have a poor prognosis. The majority of brain cancer cases cannot be explained by any specific underlying medical or genetic conditions, environmental factors or behaviors. A...
Cancer tumors develop when cancerous cells multiply and form malignant masses of tissue. Many times these cancerous cells break away from their original mass of cells, travel through your bloodstream and lymph nodes, and implant in various organs...
Kidney cancer is one of the National Cancer Institute's (NCI) top ten most common cancers. It projects there will be 58,240 new cases of kidney cancer and 13,040 deaths from this disease. Although this disease often strikes smokers and people who...
Breast cancer originates from abnormal, cancer-prone cells that develop in the breast tissue as a result of environmental, genetic and still unknown factors. Over time, cancerous cells proliferate in specific tissues of the breast and form a solid...
Prostate cancer is the third most common cause of cancer deaths in men, according to the University of Maryland Medical Center. However, more than 90 percent of cases that are caught early are successfully treated. If you are diagnosed with...
The American Cancer Society estimates that in 2010, more than 22,000 people in the United States will be newly diagnosed with a brain or spinal cord tumor. The exact cause of brain tumors is not understood completely, but several risk factors can...
According to the National Cancer Institute (NCI), there are more than 100 different types of cancer. Cancers are categorized by the organ involved and the type of cell that gave rise to the cancer. The four overarching groups of cancerous tumors...
Testicular tumors are tumors that develop in the cells of the testicles, the egg-shaped male reproductive glands in the scrotum. There are numerous kinds of testicular tumors, but treatment with surgery, radiation and/or chemotherapy has produced...
The thyroid, a two-part gland below the larynx, regulates the body's energy level. Thyroid cancer is rare, with slight increases in recent years, which may be due to new techniques that enable doctors to find small cancers that previously couldn't...
Brain tumors can cause serious problems because of the inherent fragility of the neurons within the brain. Because neurons are generally unable to divide and reproduce, brain cancer generally is caused by abnormal cells that come from other parts...
Cayenne pepper appears to effect different cancers in different ways, and the nature of the effect depends on the stage of the cancer. Cayenne pepper contains capsaicin; traditional medicine employs this compound as an herbal remedy for the...
Breast cancer is a complex disease that is made up of many different kinds of tumors. Breast cancer tumors can usually be classified based on the tissue from which they arose. Malignant phyllodes tumors are a rare form of breast cancer.
Breast cancer is classified according to where the cancer originates. The Mayo Clinic explains that breast cancer can start in the ducts of the breast, the milk-producing lobules of the breast or, sometimes, the connective tissue that is in...
A brain tumor is an abnormal growth by the cells in the brain. The cells reproduce themselves in an uncontrolled manner. These tumors can be benign (harmless) or malignant (cancerous). Primary brain tumors are growths that started in the brain,...
Good nutrition is a key part of keeping your body strong and healthy when you have brain cancer. Cancer and its treatments can affect your appetite and make it difficult to eat well. A healthy diet can improve your energy levels, help your body...
Breast cancer originates from previously healthy breast cells that develop genetic mutations, allowing the cells to grow uncontrollably and form tumors. Breast tumors may be non-cancerous and benign, or cancerous and invasive. In some cases,...
A retinoblastoma tumor is a cancerous tumor that grows in the eye. The tumor begins growing on the retina, the lining in the interior of the eye. The retinoblastoma tumor is a rare cancer primarily found in children under the age of 5. The...
Lung cancer staging is a method used by physicians to determine how far the cancer has spread in order to provide the appropriate treatment intervention. According to Cancer Research UK, the process of staging provides information on the size of...
The American Cancer Society states that the term "brain cancer" is not used as often as "brain tumor." Even though some brain tumors are not cancerous, they can still grow and cause damage to the brain and other problems throughout the body. When...
Each tissue in the body receives a supply of oxygen-rich blood from the arteries, which is then carried back into the lungs by veins for future oxygenation. Beginning in utero, tissues throughout the body carry out angiogenesis -- the growth of...
The brain contains billions of cells, working together to support cognitive function and processes required to sustain life. Cells within the brain can be broadly classified as neurons or glia. Neurons, the nerve cells of the brain, communicate...
