Cancer is a term for diseases in which cells become abnormal and divide without order or control. These malignant cells form too much tissue and become a tumor. The tumor can invade nearby tissues and spread to other parts of the body through the...
The human body is made up of millions of cells. Although the basic structure of each cell is similar, the overall structure varies depending on the function of that cell. There are several different types of cells in the body that are classified...
Breast cancer occurs when one type of cell in breast tissue transforms from a normal cell into a cancerous cell. Every year, 192,000 woman and 2,000 men are diagnosed with breast cancer in the U.S., according to the National Cancer Institute. Just...
Radiation is a treatment designed to target and kill cancerous cells that are dividing uncontrollably in the body. Radiation can originate externally from a machine administering radiation, or internally from a radioactive substance injected into...
Selenium is an essential mineral that your body requires in very small quantities. The recommended daily intake of selenium for adults is 55mcg per day. Selenium is found in both plant and animal foods, with Brazil nuts supplying, by far, the...
Cancer is a tumor that tends to grow rapidly, can metastasize and invade nearby normal tissues, and spread to other parts of the body through the bloodstream or lymphatic system. The exact cause of cancer is unknown, but researchers believe that...
Many health experts are adding blueberries to their list of super foods, including a team of USDA nutritionists reporting in the "Journal of Agricultural and Food Chemistry," who placed both wild and cultivated blueberries as two of their top five...
Cancer begins when abnormal cells grow out of control. As cells in the body begin to die out, they divide and new cells grow to replace the dying ones. But cancerous cells do not replace themselves with new, healthy ones. Instead, they multiple...
According to the National Cancer Institute, one-third of all cancer deaths are inadvertently related to dietary habits, many from the foods that people choose to omit. An ideal cancer diet includes foods that contain a substantial amount of...
Cancer is defined as an uncontrollable growth of irregular cells in your body. Cancer cells may multiply on or in almost any tissue and organ, and the most common form of cancer in men and women is lung and colon cancer. Treating cancer may vary,...
Vitamin D is a fat-soluble vitamin that helps the body absorb calcium and maintain proper calcium and phosphate levels in blood. Vitamin D can also regulate cell growth and differentiation -- the process by which cells acquire specialized...
Cancer development and growth is mediated by many factors. Antioxidants are a potential protective factor against the development cancer. Diets that include foods rich in antioxidants, such as fruits and vegetables, have been associated with a...
Our bodies contain billions of cells, the building blocks of life. Each cell receives messages from its chromosomes about how to grow and function. Sometimes, through genetics or environment, those chromosomes receive damage and send messages to...
The cervix, which is located at the junction of the vagina and the uterus, is prone to developing cells with genetic mutations that cause them to grow abnormally quickly. Low-grade cervical cancer is dangerous because of its ability to develop...
According to the American Society of Radiation Oncologists, two-thirds of all cancers are currently treated with some form of radiation. Radiation, or "radiotherapy," may be used as the primary treatment or as an adjunct to surgery or...
Green tea is an herbal beverage made from a Chinese evergreen shrub, Camellia sinensis. It is also sold as dietary supplements in the form of capsules. It is naturally cholesterol free and delivers a hefty amount of antioxidants. Green tea...
Prostate cancer is a cancerous tumor that forms in the tissues of the prostate, a small, chestnut-shaped gland in men that produces a whitish fluid called seminal fluid, which nourishes and transports sperm. Not all tumors are cancerous; tumors...
The nutrient-rich dietary supplement wheat grass provides the essential vitamins A, C, and E as well as iron, calcium and magnesium. It belongs to a family of wheat-like grasses scientifically named Triticum aestivum, a subspecies of Poaceae, and...
Cancer, an abnormal growth of cells, may be caused by alterations of genes that keep cells from growing in the appropriate manner. Sometimes, cancer cells spread from the original site to another part of the body; this is called metastasis. Cancer...
Lung cancer can form within the air sacs or within the airways that carry air into the lungs. As the cancer progresses, the cancer eventually spreads throughout the lung tissue and leads to a buildup of fluid around the heart and lungs, called a...
The overall goal of chemotherapy drugs is to kill cells that divide abnormally. This is done by disrupting cell processes related to cell division and DNA duplication. Chemotherapeutic agents tend to group together in families based on how they...
Cayenne pepper has long been used by native peoples as a medicinal plant; it contains powerful medicinal substances you can use for a variety of purposes. No clinical evidence supports the claim that cayenne pepper kills brain cancer cells, though...
Medicinal use of olive leaf extract goes as far back as the mid 1800s, when it was as used as a treatment for malaria. A variety of active compounds have been identified in olive leaf and scientific evidence of their usefulness as antimicrobial...
You may associate lemon grass with a refreshing glass of flavored tea or a delicious South Asian meal. But this herb has some surprising properties that may one day be harnessed for therapeutic purposes. Although lemon grass is not currently used...
Skin cancer, the most common type of cancer in the United States as reported by the Skin Cancer Foundation, causes the abnormal and uncontrollable growth of skin cells. Pre-cancer cells are cells that appear abnormal but have not yet formed into...
The National Cancer Institute states there are more than 100 different diseases that fall under the category of cancer. Although cancers differ by the site of the body in which they originate and other factors, cancer cells of all types share...
There are millions of cells in the human body. In cancer, diagnosis is dependent upon the size, shape and presence of abnormal cells. The doctor runs blood tests, conducts biopsies and performs scans of the suspected area where tumor growth is...
Testicular cancer occurs in men, typically around the age of 30 when normal cells in the testis change and become tumorigenic. The majority of testicular tumors originate from germ cells. While most testicular tumors respond favorably to radiation...
According to the World Health Organization, as of 2005, there are 1.6 billion cell phone users throughout the world. Because of the proximity of the cell phone to the brain, it has been questioned whether cell phone use causes brain cancer. While...
