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.

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.

Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the eye, such as ultraviolet or infrared radiation. In general, laser radiation is not in itself harmful, and behaves much like ordinary light in its interaction with the body. Laser radiation should not be confused with radio waves, microwaves, or the ionizing x-rays or radiation from radioactive substances such as radium.

Laser medicine is a branch of photo medicine, and photo medicine is a branch of photobiology. Laser medicine is not related to allopathy, also known as the modern system of medicine, developed in the West - a system, which usually treats a disease with drugs.

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.

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.

The functioning of all parts of the human body at all levels is governed and controlled by the genes. The genes can be thought of as a large and elegant software or information store, which controls the development of human body and its normal functioning. The genes are responsible for cell multiplication, cell growth and cell death. All cancers are caused by some abnormality in the genes.

The International Agency for Research on Cancer (IARC), the Department of Health and Human Services (DHHS), and the Environmental Protection Agency (EPA) have not reviewed tetryl to determine whether it is likely to cause cancer.

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.

Cervical cancer (which the American Cancer Society says will occur in an estimated 9,710 women this year) is by far the most significant concern. However, high-risk types of HPV also have been linked to less-common cancers of the vagina (2,420 women), vulva (3,740), anus and, in men, penis (1,530). [Anal cancer is included in the numbers for vulvar cancer for women and penile cancer for men.

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.

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.

The International Agency for Research on Cancer has determined that 4,4'-methylenedianiline is possibly carcinogenic to humans. A study on people exposed to bread contaminated with 4,4'-methylenedianiline did not show an increased risk of cancer. An animal study showed cancer of the liver and thyroid after animals drank water over their lifetimes containing 4,4'-methylenedianiline.

The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the Environmental Protection Agency (EPA) have not classified Lewisite as to its carcinogenicity. Both the DHHS and IARC have classified the blister agent H/HD (the sulfur mustard used in the Mustard-Lewisite mixture) as a human carcinogen. We to not know whether the Mustard-Lewisite mixture might also be a human carcinogen.

Can inflammatory bowel disease cause colon cancer? The short answer is yes. People who suffer from inflammatory bowel disease (IBD) are at increased risk for colon cancer because the tissue of the colon is inflamed for a long period of time. Most colon cancer occurs in people with no family history of the disease. But, colon cancer can run in the family. Whether you're at increased risk depends on which family member was diagnosed and at what age.

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.

The International Agency for Research on Cancer (IARC) has classified nitrogen mustard HN-2 as probably carcinogenic to humans, based on evidence that it causes leukemia in humans and cancers of the lung, liver, uterus, and large intestine in animals.

The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the Environmental Protection Agency (EPA) have not classified phosgene oxime for carcinogenicity. There is no information to determine whether exposure to phosgene oxime might cause cancer.

The causes of ovarian cancer remain poorly understood. One hypothesis is that an increased number of ovulations increase the risk of ovarian cancer. A second theory is that high chronic levels of pituitary hormones that stimulate the ovary (pituitary gonadotropins) can somehow lead to cancer.

In India, even the highly qualified doctors do not know much about it and are unaware of the possibilities in Laser Medicine. The Indian system of medicine is largely based on British or American system and therefore Laser Medicine had been totally ignored in India till this decade. This science largely comes from Russia and few other eastern block countries. Even UK and USA are quite late to embark on Laser Medicine. The author is pioneer of Laser Medicine in India.

There is a very small risk of getting cancer from this treatment. These cancers usually take more than 10 years to develop and occur in the region that was irradiated. Your greatest risk is dying from the cancer you have now; the chance that the radiation will help you is much, much greater than it will hurt you. Unfortunately, all treatments have side effects, and we are actively researching methods of decreasing those side effects.

The "current wisdom" is that cancer begins with a single cell having abnormal genetic instructions. Over time, it (or one of its descendant cells) acquires additional injuries. Finally, a cell's abnormal instructions cause it to do abnormal things --- such as dividing too often, or forming a tumor, or migrating from its appropriate location to live and divide elsewhere in the body (metastasis). These cancerous activities are done by living cells, whose abnormalities can be caused by radiation.

In the course of mining, manufacturing and installing asbestos products, tiny asbestos fibers become airborne. Most inhaled fibers are cleared from the lungs within hours of inhalation. Coughing carries them to the throat in a layer of mucus, where they are either spit out, or swallowed, and make their way out of the body.

The International Agency for Research on Cancer (IARC) has determined that one TPH compound (benzene) is carcinogenic to humans. IARC has determined that other TPH compounds (benzo[a]pyrene and gasoline) are probably and possibly carcinogenic to humans. Most of the other TPH compounds are considered not to be classifiable by IARC.
