Incidence of Cancer is 94.2 /100000. 55.6% of cancer has been in men and 44.4% in women. The incidence rate of the most prevalent cancers is as follows: Skin (19),Breast (10.9), Colorectal (9.8), Stomach (9.8) /100000. The incidence rate of the most prevalent cancers in women is as follows: Breast (21.7), Skin (13.1), Colorectal (10) Stomach (5.9)/100000. The following findings were obtained in patients with breast cancer: The incidence of breast cancer in urban areas is 23.9/100000 and in rural areas is 15.6/100000. 96.5% of the patients were women. The average age of breast cancer has been 48 years,that is 10 years less than the global statistics. More than half of cancer(60.4%) happened in the age group of 30 to 49. Conclusions: Unfortunately, in our country the peak frequency of breast cancer among women is in the forth and fifth decades of their lives.

Therefore, it is recommended all women under 40 be examined by a physician or an obstetrician expert for one to two times a year. According to PHC in Islamic Republic of Iran, all woman over 40 should do self-examination and physical examination regularly.
