There is much controversy surrounding this question but research does not prove this to be the case. PPD's are the main source of concern and as stated above, Naturtint contains minimum levels of PPD's. Another feared chemical is resorcinol also found in most permanent hair dyes but Naturtint does not contain resorcinol (or ammonia).

NO. More than 2000 clinical studies have been conducted on the use of LILT and in all of these studies no mutational effects have ever been observed resulting from therapy with wavelengths in the red or near-infrared ranges in the doses used by laser therapy. See similar questions...

The answer is no. No mutational effects have been observed resulting from light with wavelengths in the red or infra-red range and of doses used within LLLT. But what happens if I treat someone who has cancer and is unaware of it? Can the cancer's growth be stimulated? The effects of LLLT on cancer cells in vitro have been studied, and it was observed that they can be stimulated by laser light. However, with respect to a cancer in vivo, the situation is rather different. See similar questions...

Severe, long-standing GERD can damage the esophagus and cause a condition known as Barrett's esophagus wherein the normal lining of the esophagus is replaced by a lining more like that of the stomach or intestine. It is thought that this replacement may be an attempt by the body to protect itself from further injury by acid. The risk of esophageal cancer appears to increase significantly in patients with Barrett's esophagus. The only way to diagnose Barrett's esophagus is by endoscopy. See similar questions...

There are no known causes of prostate cancer. Approximately 10 % of prostate cancers are inherited but the remaining cases occur at random. A “prostate cancer gene” has not yet been identified. There are links between diets rich in saturated fats and an increased incidence of prostate cancer but this evidence is based on epidemiologic data and not based on data obtained from clinical practices.

Gallstones are the most common risk factor for gallbladder cancer. Between 75% and 90% of people with gallbladder cancer also have gallstones and an inflamed gallbladder. Gallbladder cancer is more likely to happen if your gallbladder has a single large gallstone than several small ones. Doctors believe that large gallstones grow over a long time, irritating the gallbladder wall and increasing the risk for gallbladder cancer. See similar questions...

Laser beam is very safe because laser medicine generally utilizes wavelengths above 632 nm (nanometer). Therefore the laser beam is not ionizing radiation (which can cause cancer) like X-rays, Gamma rays etc. Sunlight contains cancer causing wavelengths (below 320 nm), which is ultraviolet. There is no certain limit for penetration of laser light. It spreads in all directions and is absorbed in tissues. Light's intensity weakens the deeper from the target point it goes.

Certain hairstyles can contribute to hair loss, most notably styles involving tight braids or pull-backs. This occurs when the hair is pulled tightly back and fastened at the base of the skull, or braided into tight braids or rows. Exposure to this type of hairstyle over long periods can result in a scarring alopecia, with no potential for regrowth.

Women want the dye to be present on the hair, but not on the scalp. Among women with other slow genes (the "CYP1A2 slow" phenotype), exclusive permanent hair dye use was associated with a 2.5-fold increased risk. find articles | submit articles | link to us | site map | terms of use | privacy policy | contact us | advertising | partner with us See similar questions...

Many women blame themselves for the development of their cancer. Of all the thousands of research studies conducted, none points to an individual woman as the cause of her cancer. It is not uncommon to feel this way after you have completed treatment. You may wish to talk over your feelings with your doctor, a counselor, or a social worker. Many women find cancer support groups to be helpful. See similar questions...

The cancer-causing potential of perc has been extensively investigated. In laboratory studies, perc has been shown to cause cancer in rats and mice when they swallow or inhale it. There is also evidence, from several studies of workers in the laundry and drycleaning industry, suggesting a causal association between perc exposure and elevated risks of certain types of cancer.

There is no established relationship between hemorrhoids and cancer. However, people often mistake signs of colorectal cancer for hemorrhoids. You should see your doctor right away if you notice any signs. Do not try to self-medicate without seeing your doctor. Time is important when dealing with cancer detection. See similar questions...

Most experts currently accept (a) the single-cell origin of a cancer and (b) the requirement for multiple genetic abnormalities in the same cell. It follows that a single case of cancer very probably has more than one cause, even if carcinogens act additively instead of synergistically. Suppose that a type of cancer requires the accumulation of 5 independent genetic injuries in the same cell. If only 4 occur, no cancer can occur. See similar questions...
