Prostate Cancer Symptoms and Treatment Options

December 8th, 2011

Prostate cancer is the leading cancer among men in North America. 80% of men over 80 will get prostate cancer. The prostate is a chestnut size gland which produces proteins and fluids to carry sperm upon ejaculation. Usually, there are no obvious signs or symptoms of prostate cancer, at least not when it is in the early stages. The cure rate is very high when it is in the beginning stages, so early detection is crucial. Treatment in the T-1 and T-2 stages has a 90% or better cure rate, so it is important to know how to take control of your prostate health and what to look for.

All men over theage of 50 should get annual screening, unless there is a history of prostate cancer in the family, at which point they should start screening at 40. The only reliable way to way to determine if prostate cancer exists is by visiting your doctor for a screening. Screening can be a relatively simple procedure which usually begins with a digital rectal examination. Your doctor will check your prostate by inserting a gloved finger into the rectum. The prostate in located below the bladder, in front of the rectum, so your doctor will be able to feel the prostate via the rectum to check for tumors. The other form of screening is a PSA or prostate-specific antigen test. The PSA test gives a reading of protein made by the prostate. A low PSA level of less than 4 ng/mL, would usually mean no further testing is required. If the PSA Levels are high, or rise over time, then your urologist will want to evaluate further.

If the tests lead your physician to suspect that prostate cancer may be indicated, a biopsy will likely be performed. This is the only sure way to diagnose prostate cancer. A local anesthetic is generally given, then an ultrasound probe is inserted to check for abnormalities. A biopsy needle is inserted to take 6 to 12 tissue samples, which are then viewed under a microscope. The tissue samples are compared to normal prostate samples, then given a Gleason score of 1 to 5, with 1 being close to normal and 5 being highly abnormal. Your doctor will determine the stage of the cancer and how far the cancer has spread. High PSA scores indicate a more aggressive cancer, with tumors more likely to grow and spread to other organs. The risk category and the need for treatment will be determined by the size and extent of the tumors, combined with the PSA levels and Gleason score.

Treatment options will vary depending on the risk category. Your age, health, race and family history will also be taken into consideration when determining the best course of action, so it is wise to research your options and discuss them with your urologist. For organ confined prostate cancer, one of the best prostate cancer treatment options is HIFU, which minimizes the possibility of risks and complications, including impotency and incontinence. HIFU is High Intensity Focused Ultrasound, where ultrasound waves are used to destroy the cancer tumors. A specially trained physician uses a computer guided Ablatherm HIFU probe which targets the tumors with pinpoint accuracy, without damaging surrounding organs or tissues. Get an annual prostate exam for early detection and learn more about the HIFU prostate cancer treatment if you are diagnosed with the disease. A healthy lifestyle and regular check ups are essential for men over the age of 50, as prostate cancer is the leading cancer for men in North America.

Colorectal Cancer Information On Symptoms And Treatment

July 19th, 2011

The incidence of cancer of the large bowel and rectum shows wide variation throughout the world. It is one of the most common internal malignancies in the United States. The mean age for onset of colorectal cancer is 63 to 67 years old. The exact cause of this type of malignancy is unknown, but it is generally accepted that it occurs more frequent on urbanized, industrialized countries and less frequently in rural and underdeveloped ones. The causes are considered to be more due to environmental factors. However, family history is also a predisposing factor.

The high bulk diet of persons in less advanced areas permits the easy, rapid passage of several bowel movements per day which is one of the tips for colorectal cancer prevention. Researchers agree that more work needs to be done, but delayed motility and bacterial activity seem to be involved in developing carcinogens. Constipation predisposes to cancer of the bowel by permitting long exposure of the mucosa to external carcinogens in the stool.

A thorough physical examination and questions about patient history are essential in determining the presence of carcinoma. The patient should be questioned about previous findings of polyps or colitis, and about a family history of colorectal and other cancers. The findings may be non-conclusive or highly suspicious. Rectal examination also reveals about 50% of cancers in the large bowel. Iron deficiency anemia in the male and post menopausal female and the presence of blood in the stool should always be investigated.

Colorectal cancer symptoms include changes in bowel habits and bleeding. Pain is even felt depending on where the cancer cells are located on the part of the colon. When it includes the rectum and the recto-sigmoid for instance, local pain or pain in the lower back that radiates down the legs. It feels like you are being zapped with a stun gun at that area. Nausea and vomiting is also common and even anorexia and anemia.

One of the most confusing aspects of large bowel cancer has been related to staging or classification of the disease. The staging is based on examination of the specimen after surgery. Numerous staging systems have been developed. The Dukes classification with three stages is simple and easy. Stage A involves the spread of the mucosa and sub-mucosa. Stage B includes the invasion through the entire muscle wall with no node involvement. Lastly, stage C includes the metastasis to regional lymph nodes.

The treatment for colorectal cancer may involve one or a combination of surgery, including laser surgery, radiation therapy which includes isotope implants and chemotherapy which also involves immunotherapy. Electric sparks almost similar or higher than the voltage used on tazer gun is applied to destroy tissues or it is medically called as fulguration. The choice of the particular modality or combination is dependent upon the type and location of the tumor, degree of metastasis and the condition of the patient.

The prognosis is dependent upon the time of detection and the treatment. That is why you must know and be vigilant when it comes to the warning signs and symptoms of this type of cancer for earlier detection and prevention.
