Professor Ian Olver, Cancer Council Australia CEO, states a net increase in lung cancer incidence in Australian women compared with men could be due to chronological differences in smoking behavior between the males and females, saying:
"Smoking prevalence in Australian men peaked in the 1940s while in women it was the mid-70s, so it's not surprising lung cancer rates in men are declining while they are on the rise in women. In the 1940s tobacco products were heavily promoted to men, while in the 1960s and '70s the tobacco companies sought to exploit the female market with brand names like "Slims", menthol cigarettes and packaging stylized to appeal to women."
According to the National Digestive Diseases Information Clearing House of the NIH, the causes of GERD remain unclear. Research shows that in individuals with GERD, the lower esophageal sphincter relaxes while the rest of the esophagus is working. In addition, anatomical abnormalities such as a hiatal hernia may also contribute and such hernias can occur at any age.
Other factors that may contribute are obesity, pregnancy, smoking and certain foods.
Chronic GERD that goes without treatment can cause serious complications such as damage, bleeding or ulcers on the lining of the esophagus or narrowing of the esophagus. Some people can develop Barrett's esophagus, in which the cells in the esophageal lining change and can eventually turn into esophageal cancer, which is usually fatal.
You do not need to have classic "heartburn" symptoms to have GERD; other symptoms include a dry cough, asthma symptoms or trouble swallowing. If you have been using antacids for more than two weeks, it's time to see a doctor.
Acid reflux is real and treatable. If you or someone you love experiences chronic heartburn, make sure you see your physician or a gastroenterologist for treatment.
NewsTarget has also learned that HPV vaccines have been proven to be flatly worthless in clearing the HPV virus from women who have already been exposed to HPV (which includes most sexually active women), calling into question the scientific justification of mandatory "vaccinate everyone" policies.
Furthermore, this story reveals evidence that the vaccine currently being administered for HPV -- Gardasil -- may increase the risk of precancerous cervical lesions by an alarming 44.6 percent in some women. The vaccine, it turns out, may be far more dangerous to the health of women than doing nothing at all.

World cancer experts have finally declared what NewsTarget readers learned nearly four years ago: That processed meats cause cancer, and anyone seeking to avoid cancer should avoid eating all processed meats for life.
Hundreds of cancer researchers took part in a five-year project spanning more than 7,000 clinical studies and designed to document the links between diet and cancer. Their conclusion, published in the World Cancer Research Fund's report, Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective (2007), has rocked the health world with a declaration that all people should immediately stop buying and eating processed meat products and that all processed meat should be avoided for life!
Women who had their tonsils removed in childhood may be at increased risk of developing pre-menopausal breast cancer, according to University at Buffalo researchers.
Study leader Theodore Brasky said an apparent association may be related to the loss of protective function of the tonsils when they are removed.
Alternatively, tonsils that needed to be removed may have been markers for severe or chronic infections in childhood, and that such infections cause inflammation that may contribute to cancer, Brasky said.
Abortion and miscarriage do not raise the risk of breast cancer, according to a study published Monday by the US National Cancer Institute in the Archives of Internal Medicine.
The 10-year study, performed on a sample of 105,716 US participants, rejects prior studies that suggested a link between prematurely terminated pregnancies and breast cancer.
The subjects were nurses aged 29-46 at the start of the study. They answered questions every two years via anonymous questionnaire about their medical history, including whether they had abortions, miscarriages and breast cancer.
"Among this predominantly pre-menopausal population, neither induced nor spontaneous abortion was associated with the incidence of breast cancer," said the study's authors from Brigham and Women's hospital and Harvard Medical School in the northeastern state of Massachusetts.
Scientists have pinpointed a set of common variations in human DNA that signal a higher risk for prostate cancer in men who carry them. Some of these variations are more common in African-American men, which may help explain why prostate cancer rates are higher in African Americans than in men of other races.
The findings, published in 3 separate studies, may lead to genetic tests that will help identify those most at risk for the disease. The findings may also help unlock the biological mysteries behind prostate cancer, which could speed up the discovery of new treatments.
The 3 studies focus on DNA variations located on chromosome 8 in some men. The variations may be linked to as many as 68% of prostate cancer cases in African Americans, 60% in Japanese Americans, 46% in Latinos, 45% in native Hawaiians and 32% in whites, the authors of 1 of the studies calculate.
