The cancer results when cellular changes cause the uncontrolled growth and division of cells. Certain forms of cancer result in visible cells growths called tumours, while others, such as leukemia, do not.
The role of the body's cells have specific functions and fixed lifespans, they provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. While it may sound like a bad thing, cell death is part of a natural and beneficial phenomenon called apoptosis, this allows to replace it with a newer cell that functions better.
Cancerous cells lack the components that instruct them to stop dividing and to die, they may appear in one area, then spread via the lymph nodes.

This was cured by chemotherapy (by pills and/or injection) who consist to kill the bad cells attempt by cancer, sadly, the chemotherapy touch as well the good cells, what it adds a secondary effect (loss of hairs, heavy tiredness…) often difficult to support.

Breast cancer is the most diagnosed cancer among women around the world.
One in 9 women will develop breast cancer in her lifetime and 1 in 27 women will die from it.
Most often, breast cancer occurs after 50 years. The 5-year survival rate after diagnosis ranges from 80% to 90%, depending on the age and type of cancer.
In recent decades, the mortality rate has declined, thanks to advances in screening, diagnosis and treatment.
This cancer can also affect men, they represent 1% of people with cancer.
