Cancer Of The Uterus – The Secret Killer
Endometrial cancer, malignancy of the lining of the womb, is the third most common cause of cancer death in women. It needn’t be. More than 35,000 American women are diagnosed every year. Other uterine cancer includes cervical carcinoma, sarcoma of the myometrium (cancer of the uterine smooth muscle) and trophoblastic disease, which arises from placental stem cells.
Most carcinomas of the lining of the womb have their origin in a thin layer of cells that line the inner surface of the uterus called epithelial cells. There are two types: Type I, which is found in women before or approaching menopause. These tend not to invade other tissue layers and their prognosis is good. Type II are mainly found in women of African-American origin who have been through the menopause. These are more serious. A less common type of cancer, endometrial sarcoma, originates from the connective tissue.
Symptoms – Vaginal bleeding is the most usual symptom that something is wrong. Women before the age of menopause may experience bleeding in between periods or heavier and longer than normal menses. Women who have been through menopause should see their doctor if they have any bleeding whatsoever. Difficulty or pain emptying the bladder, painful sex and lower abdominal pain or cramping may also be evident. Whatever the symptom, anything out of the ordinary is not something that ‘has to be put up with’ or ‘just part of being a woman’. It may be a sign of something life threatening and should be investigated.
Diagnosis – The doctor will perform an internal examination and may take blood samples to be sent off for testing. He may perform or request a vaginal ultrasound examination. This involves the insertion of a gentle probe, about the size of a tampon, and monitoring on a screen. It may be necessary to take a biopsy, either in the doctor’s office or in a hospital.
Treatment – Cancer of the cervix may be treated by radiation or cone biopsy. Endometrial cancers require a total hysterectomy and removal of both ovaries. In all cases, several years of follow-up are recommended to ensure the disease does not recur.
Causes and Risk Factors – The actual cause is not known but there are recognized risk factors. These are high estrogen levels, polycystic ovary syndrome (PCOS), difficulty conceiving or no history of pregnancy, early onset of menstruation or late cessation of periods (menopause). Other risk factors are cancers of the breast or ovaries, use of Tamoxifen (a cancer drug), pelvic radiation, being over the age of 35, diabetes or a history of anovulatory menstrual cycles.
Prevention – Some risk factors can be reduced by the individual. These include high blood pressure (hypertension), obesity, a high fat diet (in particular, animal fats). A high daily consumption of alcohol may also elevate the risk.
Heavy menstrual periods, pain and bleeding after menopause are not normal and not something that women have to put up with. Symptoms should never be ignored. There are a lot of innocent and easily treatable conditions that share these symptoms but it is impossible to tell without the necessary diagnostic procedures. Never make the assumption that there is no thing seriously wrong.

How Is Cancer Treated?
Cancer treatment depends on the type of cancer, the stage of the cancer, age, health status, and additional personal characteristics.
There is often a combination of therapies and palliative care because there is still no single way How is cancer treated. Treatments are usually devided into categos:
• Surgeryrie
• Radiation
• Chemotherapy
• Immunotherapy
• hormone therapy (gene therapy).
Surgery is the oldest treatment used even when people didn’t know all about cancer. If a cancer has not metastasized, it is simple to understand How is cancer treated, it is possible to completely cure a patient by surgically removing the cancer from the body.
But after the disease has spread, however, it is nearly impossible to remove all of the cancer cells. Surgery may also be instrumental in helping to control symptoms of cancer.
Radiation treatment, also known as radiotherapy. How is cancer treated by the radiation? It destroys cancer by focusing high-energy rays on the cancer cells.
Radiotherapy utilizes high-energy gamma-rays that are emitted from metals such as radium or high-energy x-rays that are created in a special machine. In the past radiation treatments caused severe side-effects because the energy beams would damage normal, healthy tissue, but now the beams can be more accurately targeted.
Chemotherapy- another way of cancer curing – utilizes chemicals that interfere with the cell division process – damaging proteins or DNA – so that cancer cells will commit suicide. Chemotherapy is generally used to treat cancer that has spread or metastasized because the medicines travel throughout the entire body. It is a necessary for some forms of leukemia and lymphoma. The common side effects are hair loss, nausea, fatigue, and vomiting.
Immunotherapy makes the body’s immune system to fight with the cancer. It improves cancer-fighting abilities by stimulating the entire immune system, and it can be considered targeted if the treatment specifically tells the immune system to destroy cancer cells. Bone marrow transplantation (hematopoetic stem cell transplantation) can also be considered immunotherapy because the donor’s immune cells will often attack cancer cells that are present in the host.
When people studied all about cancer hormone way How is cancer treated was designed to alter hormone production in the body so that cancer cells stop growing or are killed completely. Breast cancer hormone therapies often focus on reducing estrogen levels and prostate cancer hormone therapies often focus on reducing testosterone levels. In addition, some leukemia and lymphoma cases can be treated with the hormone cortisone.
Gene therapy replaces damaged genes with ones that work. For example, researchers are trying to replace the damaged gene in DNA that signals cells to stop dividing with a copy of a working gene. Other gene-based therapies focus on further damaging cancer cell DNA to the point where the cell commits suicide. Gene therapy is a very young field and is still developing.

Dangers Of Getting Lip Cancer – Common Kind Of Skin Cancer
When we think of skin cancer, we don’t usually thing of lip cancer. However, is more common than most of us realize. It is the most common form of oral cancer.
Most lip cancers start in squamous cells. These are the thin, flat cells that line our lips. These cancer cells, also known as squamous cell carcinomas, usually begin in areas of leukoplakia (white patches of cells that do not rub off). Interestingly, this type of skin cancer usually happens on the lower lip.
There are certain groups of individuals who are at a greater risk than others for developing this kind of skin cancer. This group would include males, people over the age of 40. It would also include individuals who use tobacco or alcohol products or have a history of head or neck cancer. Having said that, anyone is at risk of developing cancer.
Lip cancer has the same risk factors as other kinds skin cancer. The highest risk factor for all forms of skin cancer is the sun. Fortunately, this is one risk factor that we can control. Simply by using good sun blockers that have been formulated to protect the lips can go a along way in protecting them from UVA/UVB exposure.
Another risk factor associated with this type of cancer is being infected with human papillomavirus (HPV).
A sore on the lip or in the mouth that does not heal or a white or red patch on the gums are some of the early symptoms of lip or oral cancer. Bleeding, pain or numbness in the lip or mouth would be other symptoms. As well, a lump or thickening on the lips or gums would be an indication that there was a problem.
It should be noted that lip cancer may not have any symptoms and is often found during regular visits to the dentists. Also, the above mentioned symptoms may be an indication of other medical conditions.
If you are having any of these signs be sure and have them checked out.
To correctly diagnoses this kind of skin cancer it is important/spin] for you to have a physical examination of the lips and oral cavity. An endoscopy and x-rays to the head, neck and chest area are often [spin]ordered as part of the diagnosing procedure. A PET scan may also be ordered. A biopsy or a procedure to collect cells for the lip or oral cavity may be given.
There are certain considerations that affect the prognosis. How advanced] the cancer is at and where the tumor is [located in the lip will determine the rate of recovery.
Treatment options will depend on the how advanced the cancer is, the size of the tumor and where it is located in the lip or oral cavity. Also, whether the patient’s appearance and ability to talk and eat can stay the same will all be considered.
Like all other forms of cancer there is a risk that lip cancer will spread to other areas of the body. Don’t overlook any irregularities that may indicate there is something not normal. The sooner lip cancer or any other type of cancer is diagnosed the greater the survival rate. Don’t put off going to your doctor to get these irregularities checked out.

Wyeth’s HRT Drug Increases Risk of Death From Lung Cancer
Women who take the hormone replacement therapy (HRT) drug Prempro not only increase their risk of breast cancer, but their risk of death from lung cancer as well, according to a study conducted by researchers from the Medical Center at the University of California-Los Angeles and presented at a meeting of the American Society of Oncology.
“This is a new finding that tells us women who smoke shouldn’t take estrogen and progestin for menopause symptoms,” said study author Rowan Chlebowski.
Prempro, manufactured by Wyeth, was a best-selling treatment for the symptoms of menopause until 2002, when the Women’s Health Initiative study revealed that HRT significantly increased women’s risk of breast cancer and cardiovascular disease. Sales of the product plunged, although it still generated $1.1 billion for the company in 2008.
Menopause can lead to unpleasant symptoms such as hot flashes, fatigue, dizziness, headaches, muscle weakness, nausea and rapid heart beat.
The current study was based on an analysis of 16,608 participants in the original Women’s Health Initiative study. The researchers found that current and former smokers who took Prempro were significantly more likely to die from lung cancer than women who received a placebo pill instead. This pattern held for non-smokers as well, although there were significantly fewer deaths than among smokers.
Nearly 80 percent of lung cancer cases in women are caused by tobacco use.
There were also more cases of lung cancer diagnosed in women taking HRT than those taking a placebo, but this difference did not achieve statistical significance.
The type of cancer in the study is known as non-small cell lung cancer, and accounts for 85 to 90 percent of all lung tumors. Both worldwide and in the United States, lung cancer kills more people than any other form of cancer. Roughly 200,000 new cases are diagnosed and approximately 160,000 people die from the disease in the United States each year.
