Cancer has become a common term nowadays as most of the people are being diagnosed with different types of cancer.
Cancer means abnormal and unregulated proliferation of cells from a specific organ with the ability to create their own blood supply and break away from the origin and spread to other parts of the body.
There will be predominant morbidity and mortality due to damage of organs due to local growth and metastases to other parts.
Normal cells stay at the place of their origin and they show controlled replication whereas the cancer cells grow uncontrollably and proliferate, travel to other parts of the body.
Below are the symptoms and warning signs of cancer
A cancer may occur due to genetic changes that lead to uncontrolled cell growth. These cells grow to form a mass known as tumor which can be benign or cancerous.
There are three main types of tumor – Benign, Premalignant and Malignant tumors
Benign: Benign tumors are not cancerous and they do not grow or spread to other regions. They do not return once they are removed.
Premalignant: In premalignant tumors, the cells are not yet cancerous, but they have the ability to become malignant.
Malignant: Malignant tumors are cancerous. The cells can grow and spread to other parts of the body.
There are more than 100 different cancers that affect people and they are mostly described by the name from which they were originated.
