Is breast cancer screening necessary?
But regular breast screening using mammograms is the best way to find early-stage breast cancers. This means treatment may be more successful. Research trials show that women who have breast screening reduce their risk of dying from breast cancer by up to 20%, compared to those who do not.
Why is it important to detect breast cancer early?
If breast cancer is found early, there are more treatment options and a better chance for survival. Women whose breast cancer is detected at an early stage have a 93 percent or higher survival rate in the first five years.
Does breast cancer show up in blood tests?
Summary: Breast cancer could be detected up to five years before there are any clinical signs of it, using a blood test that identifies the body’s immune response to substances produced by tumor cells, according to new research.
How long can you have breast cancer without knowing?
Breast cancer has to divide 30 times before it can be felt. Up to the 28th cell division, neither you nor your doctor can detect it by hand. With most breast cancers, each division takes one to two months, so by the time you can feel a cancerous lump, the cancer has been in your body for two to five years.

How long does breast cancer take to develop?
Overall, the average doubling time of breast cancer was 212 days but ranged from 44 days to 1800 days. “Doubling time” is the amount of time it takes for a tumor to double in size. But it’s hard to actually estimate, since factors like type of cancer and tumor size come into play.
