Why cancer is a molecular disease?

First, it allows faulty mutant cells to continue through the cell cycle. Second, it allows them to escape apoptosis. Third, it leads to the genetic instability characteristic of cancer cells, allowing further cancer-promoting mutations to accumulate as they divide.

What is molecular basis of cancer?

Cellular functions are controlled by proteins, and because these proteins are encoded by DNA organized into genes, molecular studies have shown that cancer is a paradigm of acquired genetic disease.

What disease category is cancer?

Cancers comprise a large family of diseases that involve abnormal cell growth with the potential to invade or spread to other parts of the body. They form a subset of neoplasms.

Are cancers tumors?

How do cancers spread?

When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.

Can cancer go away by itself?

Tumours have been known to disappear spontaneously, in the absence of any targeted treatment, usually after an infection (bacterial, viral, fungal or even protozoal).

Why does everyone have cancer now?

This is mostly due to major efforts to decrease deaths due to infectious diseases, better neonatal care, better health and sanitation, and immensely successful vaccination campaigns like that against polio. And this increase in average lifespan is the major reason we’re seeing more cancer cases in the developing world.
