What is cancer?

The National Cancer Institute notes that cancer is the name given to a collection of related diseases, where some of the body’s cells begin to divide without stopping and spread into surrounding tissues. Cancer can appear almost anywhere in the trillions of cells making the human body. Human cells normally grow and divide to form new cells as the body needs them. Old or damaged cells die and new cells take their place. When cancer develops the cells become more and more anomalous and old or damaged cells survive when they should die, while new cells form when they are not needed. The new extra cells can divide without stopping and may form growths called tumors.

What is oral cancer?

The term oral cancer includes cancers of the mouth and the back of the throat. Cancer cells can look as a growth or aching in the mouth that does not go away.


  • Inflammations/thickenings, rough spots on the lips, gums, or other areas inside the mouth;
  • Mysterious bleeding in the mouth;
  • Unexplained impassiveness, loss of feeling;
  • Determined sores on the face, neck, or mouth that hemorrhage easily and do not settle within 2 weeks;
  • An aching or feeling that something is trapped in the back of the gullet;
  • Trouble in chewing, speaking or moving the jaw;
  • A long-lasting sore throat, or alteration in voice;
  • Ear pain;
  • An alteration in the way your teeth fit with each other;
  • Intense weight loss.


The three main causes of oral cancer are:

Genetics hereditary or hormonal issue:

Hereditary or hormonal cancers are mainly caused by an inherited genomic fault. Less than 0.3% of the population is transporters of a genetic alteration that has a huge effect on cancer threat and this cause less than 3–10% of cancer. Some of these diseases comprise certain inherited changes in the genes BRCA1 and BRCA2 with a more than 75% threat of breast cancer and ovarian cancer.

Some hormones play an important role in the growth of cancer by endorsing cell proliferationInsulin-like growth factors and their mandatory proteins play the main role in cancer cell proliferation, diversity, proposing possible connection in carcinogenesis.

Hormones are significant means in sex-related cancers, such as cancer of the breast, ovary and testis, thyroid cancer and last but not least bone cancer. For instance, the daughters of a female who has breast cancer have considerably greater levels of estrogen and progesterone than the daughters of women without breast cancer.


These greater hormone levels may clarify their greater threat of breast cancer, even in the lack of a breast-cancer DNA. Likewise, men of African pedigree have considerably greater levels of testosterone than men of European descent and have a respectively greater level of prostate cancer. Men of Asian descent, with the lowermost levels of testosterone-activating, have the least levels of prostate cancer.


Exposure to specific materials has been associated with definite types of cancer. These elements are called carcinogens.

Tobacco smoke is the main cause of 90% of lung cancer. It also causes cancer of the larynx, head, neck, stomach, bladder, kidney, esophagus and pancreas. Tobacco smoke comprises over fifty known cancer-causing elements including nitrosamines.

Tobacco is accountable for about one in five cancer deaths universally and about one in three in the established world.


Lung cancer expiry rates in the US have mirrored smoking designs, with the rise in smoking shadowed by dramatic growth in lung cancer death rates and, more newly, drop in smoking rates since the 1950s followed by a decline in lung cancer death rates in men since 1990.

10% of cancers in males and 3% of cancers in females are credited with alcohol disclosure, specifically liver and digestive cancers. Cancer from occupational substance exposures may cause amongst 2 and 20% of cases, causing at least 200,000 deaths yearly. Cancers such as lung cancer can come from breathing in tobacco smoke or due to asbestos fibers, or leukemia from exposure to chemical named benzene.


Up to 10% of aggressive cancers are related to radioactivity exposure, counting both ionizing radiation and ultraviolet radiation which are not ionized. Moreover, the majority of non-invasive cancers are non-melanoma skin tumors caused by non-ionizing ultraviolet radioactive rays, mostly from sunbeams. Foundations of ionizing radiation comprise medical imaging process and radon gas.

Ionizing energy is not a chiefly tough mutagen. Inhabited contact with a certain chemical like radon gas, for example, has similar cancer hazards as passive smoking. Radiation is a more powerful source of cancer when joined with other carcinogens such as radon plus tobacco smoke.

Radiation can cause cancer in utmost parts of the body, in all wildlife and at any phase. Children and youths are twice as likely to grow radiation-induced leukemia as adults; radiation contact before birth has ten times the result.

Therapeutic use of ionizing energy is a small but rising source of radiation-induced cancers. Ionizing radiation may be used in order to treat other cancer types, but this may prompt a second type of cancer. It is also used in few types of medical imaging.
