The War on Cancer Continues

The War on Cancer wages on and forty years after President Nixon signed the National Cancer Act into law, some big successes have followed; Breast cancer deaths fell about 28 percent from 1990 to 2006, while deaths from cervical cancer have dropped nearly 31 percent.

Colorectal deaths have fallen 28 percent in women and 33 percent in men; deaths from leukemia have fallen nearly 15 percent in women and 10 percent in men; and deaths from stomach cancer have fallen 34 percent in women and 43 percent in men.

Many more men are also surviving prostate cancer, with death rates falling 39 percent.

The National Cancer Act promised more funding for cancer research and prevention. Since then, death rates for many cancers have dropped significantly. From 1990 to 2007, death rates for all cancers combined dropped 22 percent for men and 14 percent for women, resulting in nearly 900,000 fewer deaths during that time, according to the report.

Today, more than 68 percent of adults live five years or more after being diagnosed, up from 50 percent in 1975. The five-year survival rate for all childhood cancers combined is 80 percent, compared to 52 percent in 1975.

There are about 12 million cancer survivors living in the United States; 15 percent of them were diagnosed 20 or more years ago.

Cancer is on the Rise World Wide

Cancer rates in the world are on the rise.

To the alarm of the World Cancer Research Fund, 2.8 million new cancer cases have developed due to lifestyle changes.

“As countries become more urbanised, they become more prone to the Western diseases that we are used to seeing. Not just cancers – coronary heart disease, diabetes, obesity and lung diseases.”

He said: “Many people are still unaware that risk factors such as alcohol and obesity affect cancer risk, while from television advertising to the pricing of food, our society works in a way that discourages people from adopting healthy habits.”

Obesity Hurts Everyone

If you think that being overweight effects only the obese then think again.

Obesity is fast replacing tobacco as the single most important preventable cause of chronic non-communicable diseases, and will add an extra 7.8 million cases of diabetes, 6.8 million cases of heart disease and stroke, and 539,000 cases of cancer in the United States by 2030.

Some 32 percent of men and 35 percent of women are now obese in the United States, according to a research team led by Claire Wang at the Mailman School of Public Health in Columbia University in New York. They published their findings in a special series of four papers on obesity in The Lancet.

Green Tea Lowers Cholesterol

The good news is that drinking green tea can lower cholesterol.

Good because we can all do it.

Green tea is accessible and affordable. It also, makes a great replacement for sugary caffeinated drinks because it offers a lift with just a hint of caffeine along with cancer fighting, fat busting polyphenols and flavonoids

Advocates say green tea’s heart-healthy benefits are due in part to a large concentration of polyphenols, which block the absorption of cholesterol in the gut. But skeptics argue that any beneficial effect would be small, and the side effects from a few too many cups a day not worth it.

As part of a healthy diet and lifestyle, the benefits of green tea are hard to ignore.

HPV Test Better Than Pap Smear for Cervical Cancer Screening

The HPV test for cervical cancer seems to be a better predictor of pre-cancerous lesions than a pap test alone.

Under cervical cancer screening guidelines issued by the American Cancer Society in 2002 and the American College of Obstetricians and Gynecologists in 2003, women aged 30 or older should have both a Pap test, also known as a Pap smear, as well as an HPV test, also called an HPV co-test. HPV is the most common sexually transmitted infection, and certain strains of the virus can cause cervical cancer.

Under current guidelines, if the results of both tests are normal, a woman can wait three years for her next Pap test, which looks for signs of cancer in cells from a woman’s cervix.

For this slow growing cancer, early detection is key.
