Cancer starts from the genes of one abnormal cell.
In a normal cell, there are genes that control how the cell divides and multiplies – a cell becomes abnormal if those genes are damaged or mutated.
This causes the cell to start multiplying out of control, to form a cancerous (malignant) tumour.
This tumour can form a lump or a patch of cells that can be seen on a scan.
In short, to the medical profession, cancer is essentially a disease of the cells.
If cancer occurs in the cells of the skin, then the person has skin cancer; if it is in the cells of the breast, then it is breast cancer.
But, cancer could be more than just abnormal cells.
It may be due to work stress.
It could be linked to conflict with others.
It could be related to the environment.
Hence, a holistic approach to cancer treatment is essential.
