Cancer Cure Now

Tumors begin to grow when cells multiply rapidly without control. Normally, the body maintains a system of checks and balances on cell growth so that cells divide to produce new cells only when required.

Disruption of this system results in uncontrolled division and proliferation of cells which eventually forms a mass known as a tumor. Tumors are classified as benign or malignant, though the word "cancer" refers to tumors that are considered malignant.

Benign tumors are often removable (depending on location) and do not spread to other parts of the body.

Malignant tumors grow aggressively and invade surrounding tissues of the body, and also travel through the bloodstream or lymphatic system to other sites, a process called metastases.

The basic cause of uncontrolled cell division is thought to be genetic mutation, caused by pollutants (such as tobacco smoke), inherited genetic defects (BRCA1 or BRCA2 breast cancer genes), and in rare cases infectious agents (such as the human papilloma virus linked to cervical cancer, and helicobacter pylori with stomach cancer).
