“Since 1990, over 6 million Americans have died of cancer, more than the combined casualties from the Civil war, WWII, and the Vietnam and Korean conflicts combined” (Faguet, p. 5). According to American Cancer Society projections, there were 1,529,560 new cases of cancer in 2010. Cancer is becoming more and more common around the world. New cancers are constantly being discovered. Researchers are finding new ways to detect cancer and treat it so that the fatality rate does not rise. However, there are some cancers that researchers have not yet discovered a cure for. It is very important for Cancer Research to continue so that one day these cancers will no longer be a treat.
Though there are many types of cancers, there are four main cancers that effect today’s society. These cancers include prostate cancer, breast cancer, lung cancer and colon/rectum cancer. Of the 1,529,560 new cases of cancer in 2010, 217,730 were prostate cancer, 209,060 were female breast cancer, 222,520 were lung cancer, and 142,570 were colon/rectum cancer. The majority of people who have cancer will have one of these types of cancer.
Prostate cancer is one of the most common cancers in men. This cancer effects a gland only in males called the prostate. This gland can be found in below the bladder and in front of the rectum. The purpose of the prostate is to make a portion of the fluid that protects and nourishes sperm cells in semen. The urethra runs through the prostate and carries urine and semen out through the penis.
Almost all prostate cancers develop form the gland cells in the prostate that make the seminal fluid. While some prostate cancers can grow rapidly, most are slow grow. This cancer can grow so slow that older men who have died from othe...

...obules, paget disease of the nipple, which starts in the breast ducts and spreads into the nipple, and inflammatory breast cancer, which makes the breast very tender to the touch instead of forming a lump.
Breast cancer I often caused by inheritance. A mutated gene for breast cancer is passed down to other generations. This makes a person for likely to acquire breast cancer. Some breast cancer is caused by acquired mutations to the breast tissue from radiation, or cancer-causing chemicals. The most common treatment for breast cancer is surgery. This is the removal of partial, or all of the affected breast. This can seem like drastic measures for most women because they are having a part of them that makes them women taken away. Therefore, other forms of treatment include, radiation therapy, chemotherapy, hormone therapy, targeted therapy, and bone-directed therapy.
Benign prostatic hyperplasia (BPH) is one of the most common ailments that affect aging men. Statistics show that more than half of the entire male population aged 65 have some form of BPH, while about 90 percent of men aged 85 have the condition. Every year, in the United States alone, about a quarter of a million surgeries are performed to correct BPH. As they name implies, BPH is a non-malignant growth of the prostate, the gland that secretes semen, the fluid that transports sperm. Although not harmful, BPH can bring about symptoms that could largely affect the quality of life of its sufferers.
Prostate cancer has been the number one diagnosed cancer today. According to the World Health Organization, approximately one in every ten American men will develop prostate cancer during his lifespan. This cancer has been very common in the last few years. American Cancer Society reported over 200,000 new cases of prostate cancer. Huge number of population suffered severely. The prostate is significant for reproduction. It helps the substances that are involved in fertilization and transporting of sperm as well as survival. Prostate tumor is developed in the prostate gland, which is found in the men’s reproductive system. Prostate is the size of a walnut, which is located inferiorly in the penis and anterior to the rectum. It contains the connective tissue, which includes the glandular and fibrous tissues. This tumor starts to develop during their adolescent year due to the control of the male reproductive hormones. When the tumor starts to develop, it begins at the urethra, which is a tube that releases the urine from the bladder. The tumor is a slow development yet it is contagious to the other parts of the body, such as it does affect the pelvic bones, lungs, liver, and the lower vertebrae (Zenka, 2009).
Testicular cancer is only present in males because only males have testicles. About 8,820 cases of testicular cancer are diagnosed every year. About 380 men die from testicular cancer each year. This is actually a very high survival rate. Also, the risk of a man dying from testicular cancer is about 1 in 5,000 because it is highly treatable and sometimes can be curable. It seems that the group most affected by testicular cancer is middle aged men, the average age to be diagnosed is 33. Only 6% of testicular cancer cases occur in children and teens, and about 7% of testicular cancer cases are men above 55 years old. All in all, testicular cancer is a type of cancer only in males and starts off in the testicles. It is not that common and the survival rate is very high because of the technology and doctors of today.
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.
There are many different reasons that woman maybe at a higher risk for breast cancer than other woman. Family history is risk factors that increase a woman’s likelihood of getting breast cancer. What this means is if a woman is in a family where this disease is common among female or even males they are at a higher risk for being diagnosed with breast cancer than someone who is in a family where breast cancer is not common. If the relative that has this disease is one that is very close meaning they are either a sister, mother, or daughter the likelihood that said person will also contract the disease is then doubled. This is mainly due to the fact that in close relations you are able to inherit the genes BrcA-1 or BrcA-2, these genes are mutation genes that play a role in controlling the growth of cancer cell. Only a small portion of women inherit this gene about 1 in 500 to be exact, however when they do inherit this gene they have a 80% chance of developing breast cancer in their lifetime. This gene causes woman to develop cancer at a younger age usually before the time they hit menopause. Also, women with this gene have a greater risk of developing cancer in both breasts which is called bilateral breasts cancer. This is due to the fact that once the cancer develops in one breast the risk for developing it in the other breast increases. (“Breast Cancer”) "About 5 to 10% of breast cancer is hereditary, passed from one generation to the next via a variety of mutated genes". (Port 95-105) Lastly,

The growth and development of prostate is controlled by the male hormone, testosterone and its active metabolite, dihydrotestosterone (DHT). Testosterone is converted to DHT by an enzyme called 5 alpha reductase.
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 signals that initiate the formation of new blood vessels. (CaP CURE,2000,p1) With the increasing rate of prostate cancer in males it is highly suggested that men begin to get tested for this form of cancer at the age of 30. There are two ways of diagnosing prostate cancer. The most common way is a rectal exam. Digital rectal examination can provide meaningful information in both the diagnosis and staging of prostate cancer. (Ernstoff,Heaney,Peschel,2,p48) The exam is fairly simple. A doctor places his finger in the anus and feels for the texture and size of the gland. The second way that a physician can determine if a male has prostate cancer is the PSA test, which measures the levels of the enzymes produced in the prostate. A method that is not widely used is an ultrasound to visualize the prostate. The rate in which the prostate grows can be reduced through the controlling of testosterone. Yet the prostate can never be stopped from growing and at some point it will grow uncontrollable and can be deadly. After a male is diagnosed with prostr...
Cancer develops when cells in a part of the body begin to grow out of
Over the past few decades, cancer has become a very prominent disease. There are many different types of cancer and many different causes of the the disease. Most cancers are caused by a genetic mutation. The most common type occurs when a cell is divided. Proto-oncogenes, which are alleles in normal cells, mutate to form oncogenes.
Another test for early detection of prostate cancer has been the digital rectal exam (DRE). Although DRE is a better method for early detection, it is also a hindrance among men, particularly African-American men, to screening and early detection (Plowden, 2009). According to American Cancer Society (ACS) and American Urological Association (AUA), the PSA and DRE should be offered annually for all men beginning at age 50 (Gray, 2009). However, they also recommend that African-American men with a family history of prostate cancer should begin testing by age 45 (Plowden, 2009). However, due to the cultural barriers to prostate screening such as lack of understanding, traditions, mist...

Prostate Cancer: Prostate cancer is a cancer that affects your prostate gland. Men should be aware. Looking for symptoms in a good way to see if you many have it, because the sooner the better. This cancer is a common cancer found in men.
Benign Prostatic Hyperplasia The prostate is a gland that is only present in men. As they age, the gland may begin to grow and may eventually cause problems with urination, because the gland pinches off the urethra as its size increases. Some problems that may be caused by a benign prostatic hyperplasia are a weak or interrupted urinary stream, difficulty starting the urine flow, even when the bladder feels full, and a feeling the bladder is not completely empty. Erectile dysfunction Penis health is very important for men.
