Prostate Cancer The prostate gland is an egg-sized organ that rings the male urethra. The secretions of the prostate give nutrients to the semen. Prostate cancer is the most commonly diagnosed cancer and the second most common cause of cancer death in men. (Ernstoff,Heaney,Peschel,1998,pviii) Like all cancers, prostate cancer is an uncontrolled cell production in a particular organ or area of the body. In the case of prostate cancer, these cells begin to split impulsively in the prostate and form tumors. As these tumors begin to grow they begin to use up oxygen from other healthy cells and surrounding tissue. Not only do these tumors take up oxygen from other cells, they secrete protein sign ...

Prostate Cancer Prostate Cancer Cancer of the prostate, a common form of cancer, is a disease in which cancer (malignant) cells are found in the prostate. The prostate is on the male sex glands, and is located just below the bladder and in front of the rectum. The size of the prostate is about the size of a walnut. It surrounds the part of the urethra, the tube that carries urine from the bladder to the outside of the body. The prostate makes fluid that becomes part of the semen, which contains sperm. Prostate cancer is most commonly found in older men. As a man gets older, his prostate may get bigger and block the urethra of bladder, which can cause him to have difficulty urinating or even ...

Prostate Cancer The prostate is a gland that is located just underneath the bladder. It surrounds the urethra through which a man urinates. The prostate gland is therefore vital to proper bladder control and urine flow-rate. The prostate is also essential for normal sexual function. It is the gland of ejaculation, supplying 95% of the seminal fluid and the power to push it through the urethra and out of the penis. The normal prostate in an adult man is about the size of a walnut. Its size often increases over time, however, particularly once a man gets beyond age 40. Because the urethra runs right through the middle of it, a growth spurt of the prostate will squeeze the urethra and begin to ...

- Agent Orange - 973 words
Agent Orange In 1962, the United States Military began to use a potentially toxic chemical known as Agent Orange. The toxic chemical was used a defoliant to destroy crops and eliminate ground cover during the Vietnam War. Vietnamese troops would hide underneath the thick forest and make it impossible for United States troops to spot them. So in 1962 the Army began using Agent Orange as a way of eliminating that problem. The government had very little knowledge about the deadly chemical but went ahead and used it anyway. They had no idea of the disastrous long-term effects that it would have on men, women and children. But the hardest group hit by the chemical was not Vietnamese civilians but ...

Brca1 & Brca2 Are Women More Susceptible to Breast and Ovarian Cancer If a Mutation in BRCA1 and BRCA2 is Found Breast and Ovarian cancer are the two most common kinds of cancers found in women in the United States. An estimated 90-95% of cancer cases are believed to be environmental and lifestyle related. The remaining five to ten percent of these types of cancers may be caused by inherited genetic mutations. The existence of a breast cancer susceptibility gene known as BRCA1 and its approximate location on human chromosome 17 have been known for about 4 years, on the basis of retrospective family studies. But only since 1994 have scientist actually been able to isolate and sequence the gen ...

- Cancer - 1,487 words
Cancer Introduction According to Mollet, cancer is the second leading cause of death in the United States. Estimates for 1982 indicate that 430,000 Americans will have died of some form of cancer. If national trends continue, some fifty-three million Americans now alive will contract cancer sometime during their lifetime. Of this inverse number, approximately one-half will die of cancer despite a medical effort to cure and prevent cancer (300). Although 45 percent of the detected cases of serious cancer are curable, an increase of 5 percent in the last ten years, it is obvious that measures can be taken to increase the cure rate and also prevent onset of various cancers. Clark suggested that ...

- Childhood Obesity - 1,051 words
Childhood Obesity In today's society childhood obesity is considered to be an epidemic. The increase in obesity is not caused by the change in the gene pool, but rather by the change in the environment. This causes vulnerable populations to express the obesity phenotype (Stune, 1999). One in seven children ages 6-17 are considered to be obese. Most nutritionists will say that this is do to the lack of parental guidance. A child's parents should teach their child proper eating habits so that they won't run across problems in the future (Tomlin, 1999).

- Germ Line Gene Therapy - 1,549 words
Germ Line Gene Therapy Whether it is referred to by its scientific term syngamy or by the general term conception, the moment a sperm cell unites with an egg cell stirs, both in the scientist and the layperson, much awe and reverence. It is the point at which a new and unique genome is created. To some it is the instant a new person comes into existence. Such a union has been repeated for billions of years since its advent in the first, simple organisms. It is a means by which evolution can exert its influence. When the genetic material of two individuals combine in sexual reproduction, any variations between the two inherited sets of genes may result in offspring that are more or less suite ...
