Keighley Richardson- National Cancer Trends



Cancer Trends in the United States
Three of my immediate family members have been diagnosed with three of the most prevalent forms of skin cancer in the United States. My mom, dad, and brother have been diagnosed with breast cancer, malignant melanoma, and basal cell carcinoma, respectively. Since my life has been directly impacted by cancer, I wanted to research cancer trends across the U.S. for my community trends assignment. In order to gain more information, I called the National Cancer Information Center and spoke to Chris Smith, one of the Cancer Information Specialists employed there. Chris gave me a lot of useful information about the current cancer trends and the five most common types of cancer in the Unites States. The three most prevalent cancers for both sexes in order of occurrences are skin cancer, lung cancer, and colorectal cancer, with prostate cancer and breast cancer as the most common cancers for only men and women respectively.

Skin Cancer
            Skin cancer, the most common form of cancer across the United States, comes in three forms. The most common form is basal cell carcinoma, followed by squamous cell carcinoma and then the most lethal, melanoma. It is so common, in fact, that most organizations don’t even keep an exact count on the number of occurrences they see each year. In the last year, however, there were at least 3.5 million people diagnosed with carcinomas, and the number is expected to rise. A trend has also been observed in an increase in carcinomas among women, and although no solid evidence has been researched, it is thought to be due to an increase in sun exposure and the use of UV lamp tanning beds. Unlike most other forms of cancer, skin cancer is common among all age groups, though depending on a person’s race, gender, and age, their chances of contracting a carcinoma or melanoma may be increased.

Lung Cancer
            As the second most common type of cancer in the U.S., lung cancer is preventable in about 87% of cases. Tobacco use is the number one preventable cause of death in the United States, and has actually been on a steady decline since 1964 when the surgeon general first spoke against tobacco. The trends among the different age groups have been fluctuating, but the overall use of cigarettes has decreased in recent years. However, 44 million American adults are still smoking today, which helps account for the number of cases reported each year. In 2013, it is predicted that there will be around 230,000 new cases of lung cancer, and over 150,000 deaths. The demographic is generally predominantly male, and is more common in those who smoke over nine cigarettes a day.

Colorectal Cancer
            Colorectal cancer is the third most common cancer among both genders in the United States. It is estimated that about one in every twenty adults will develop colorectal cancer at some point in their lives, although certain factors can increase a person’s propensity for contracting the disease. A few of these are lifestyle, weight, regular exercise (or lack of), family history of colorectal cancer, heave alcohol use, diets high in red meat, and those with irritable bowel disorder. In 2013, it is expected that over 100,000 new cases of colorectal cancer will be reported, with more men being diagnosed than women. The odds are that 9 out of 10 people diagnosed will be over the age of fifty, since incidences increase with age. Early detection and regular screenings have helped lower the number of deaths in recent years, and are ideal ways to prevent fatalities due to colorectal cancer.

Prostate Cancer
            The number one most common form of cancer in American men is prostate cancer. Last year about 230,000 men were diagnosed, and around 30,000 died as a result of the disease. About 1 out of every 6 men will be diagnosed with prostate cancer, and of those men, two thirds will be men age 65 or older. Prostate cancer is the second leading cause of death in American men, following lung cancer. However, there are 2.5 current prostate cancer survivors in the United States as of the new year. This high number is largely due to advances in surgery and treatment options, as well as implementing the wait and see technique more often instead of simply jumping straight into surgery.

Breast Cancer
            The most common type of cancer among women in the United States is breast cancer. Around 1 in every eight women will likely develop this specific type of cancer in their lives. It is estimated that there will be around 230,000 new cases in the year 2013 alone. The incidence rate has, however, decreased in recent years, dropping 7% from 2002 to 2003 alone. This is probably linked to the initiative to reduce hormone treatments in post-menopausal women, since this increases their risk of developing cancer. Deaths due to breast cancer have also been reduced to about 1 in 36 cases due to early detection, increased awareness, regular screenings, and improved treatments. Today, there are about 3 million breast cancer survivors in the United States.
