[117] conducted studies on breast self examination and health beliefs of Turkish women and stated that physical illnesses and early death can be prevented by early diagnosis of breast cancer.
How has breast cancer treatment changed?
Treatment for breast cancer has evolved over time. Breast cancer was originally treated as a local disease, and the primary treatment was radical surgery. Over time, radical surgery evolved into more breast-conserving surgery known as lumpectomy. Radiation was used to control the local/regional disease.
How has breast cancer treatment improved over the years?

Over the last 10 years, many researchers with ACS grants have contributed to that growth.
How has cancer treatment evolved as scientists have learned more about cancer?
As scientists have learned more about the basic mechanics of cancer cells – particularly the molecular changes that allow normal cells to become cancerous and to grow and spread in the body – they've found new ways of intervening in the cancer process.
Can Stage 4 breast cancer be cured?
While treatable, metastatic breast cancer (MBC) cannot be cured. The five-year survival rate for stage 4 breast cancer is 22 percent; median survival is three years. Annually, the disease takes 40,000 lives.
What happens after 5-year survival rate?
Cancer survival rates often use a five-year survival rate. That doesn't mean cancer can't recur beyond five years. Certain cancers can recur many years after first being found and treated. For some cancers, if it has not recurred by five years after initial diagnosis, the chance of a later recurrence is very small.

What is the term for the time it takes for a tumor to double in size?
Tumor doubling time is the period of time that it takes for the tumor to double in size. Since it would be unethical to leave a cancer untreated to see how rapidly it grew, doubling time is estimated in a number of ways. Looking at these estimates, however, doubling times have varied widely from study to study.
How to estimate doubling time?
Looking at these estimates, however, doubling times have varied widely from study to study. A 2019 study estimated doubling time by looking at serial ultrasounds between diagnosis and surgery. It was found that growth varied significantly based on the estrogen receptor status of the breast tumors.
