Cancer is a genetic disease caused by changes to genes that control cells function, especially how they grow and divide. Unexplained weight loss, fever, fatigue, skin changes, unusual immune system reactions, brain, and nervous system problems, chemical changes in your body, unusual bleeding or discharge etc are Symptoms of any kind of cancer.

These are the common symptoms with cancer, but there are many other symptoms that are not listed here.
Consult your doctor if you find any major changing in your body and lasts more than two weeks.

What is Cancer?

Cancer is the name of a group of many related diseases. Cancer is linked to the cell, In every form of Cancer body’s cell do not grow normal but spread very fast. Cells start to divide without stopping(uncontrolled way) and spread into surrounding tissues.

Your body is made up with trillions of cells, Cancer can occur anywhere in the body of a human. In normal, about 300 Million Cell dies in your body every minute, when cells grow old or become damaged or exhausted, they die, and new Cells grow and divide to form new cell as to replace dead or damaged Cell.

In Cancer, Cells become more abnormal, old or damaged cells survive when they should die and new Cells form when they are not needed. Cells continue to grow without stopping and form growths called tumors.

Most cancers form solid tumors, which are masses of tissue. Cancers of the blood, generally do not form solid tumors, such as leukemias. Cancerous tumors are malignant.

Sometimes cancer cells break away from the original tumor and travel to other parts of the body, where they keep growing and can go on to form new tumors. This is how cancer spreads. The spreading of a tumor to a new place in the body is called metastasis.

How Cancer Occurs?

Cancer is a genetic disease caused by changes to genes that control cells function, especially how they grow and divide.

Genetic changes that cause cancer could be inherited from our parents. Genetic changes also arise during a person’s lifetime as a result of errors that occur as cells divide or because of damage to DNA caused by some environmental exposures. Cancer-causing environmental exposures include substances, such as the chemicals in tobacco smoke, and radiation, such as ultraviolet rays from the sun and Pesticides, fertilizers etc.

We should keep in mind, though, that in the majority of cancer cases we cannot attribute the disease to a single cause.

We can generally divide cancer risk factors into the following groups:

Lifestyle-related some factors that cause cancer include:
• tobacco
• alcohol
• UV radiation in sunlight
• some food-related factors, such as nitrites and polycyclic aromatic hydrocarbons (PAHs) generated by barbecuing food).

Cancer-causing some factors related to our working and living environments include:
• asbestos fibers
• tar and pitch
• polynuclear hydrocarbons (e.g. benzopyrene)
• Some metal compounds
• Some plastic chemicals (e.g. Vinyl chloride)

Bacteria and viruses can cause cancer:
• Helicobacter pylori (H. pylori, which causes gastritis)
• HBV, HCV (hepatitis viruses that cause hepatitis)
• HPV (human papillomavirus, papillomavirus, it is a viral infection which causes changes eg. Cervical cells).

Radiation can cause cancer:
• ionizing radiation (e.g. X-ray radiation, soil radon)
• non-ionised radiation (the sun’s ultraviolet radiation)

Some drugs may increase the risk of cancer:
• certain antineoplastic agents
• certain hormones
• medicines that cause immune deficiency
