Dr. Rano Azimova, a specialist in malignant tumor oncology and surgery, revealed the main factors causing the development of breast cancer.

The specialist pointed out in an interview with "Izvestia" newspaper that the main factors affecting the development of breast cancer, which is the most common, are hormonal imbalance, environmental pollution, and the quality of the food consumed by women.

She added that these factors are usually detected in women in large cities. She indicated that malignant tumors can develop as a result of early onset of menstruation, delayed menopause, as well as harmful environmental factors, therefore she calls for regular annual check-ups.

The specialist had previously revealed the symptoms of a brain tumor, which are headache, dizziness, nausea, vomiting, seizures, speech disorder, and weakness in the arms or legs, noting that this depends on the location of the tumor in the brain.
