Impact of Physical Activity and Associated Factors on Breast Cancer: A Comprehensive Review

Breast cancer is described as a nomadic growth and proliferation of cells that occurs in breast tissues. There are many tumors that are benign in the breast due to soft tissue, which are also considered non-cancerous. For example, fibrocystic changes aren't actually a cancer condition. Breast cancer is the commonest disease worldwide. This is becoming most common disease related to female mortality worldwide. Breast cancer is the deadliest disease in women. Most cancers can be cured through surgery. Clinical methods consider breast cancer to be a heterogeneous disease. The identification of expression profiles for genes has been categorized into two main groups. This group is dependent on estrogen receptors known as ER. The tumors in the breast are associated with ER expression that expresses hormone-related factors. In developed countries, the mortality threshold, especially due to breast cancer survivors, is very low. Like lung cancer in developed countries, leading cause of death is becoming breast cancer but not more so, it also causes female deaths in developing countries. There has been some encouragement in the mortality and incidence rates of breast cancer with stable new cases. There is also a decrease in the mortality rate in some high-income and developed areas. However, the opposite occurs in the developing regions of the world. There has also been a decrease in incidents and deaths in the United States and physical activity can affect hormonal concentration and energy balance.
