2. Ovarian cancer

The mean ovarian cancer incidence per annum is 6.0 per 100,000 females in 2011. Bangkok, Lamphun and Krabi province had the highest number of incidence comparing to other provinces (ASR=7.3), while the Northeastern region had the lowest number of new cases of ovarian cancer (ASR=4.4). The incidence of ovarian cancer increased from the age of 55 years onward. This shows that there is a later onset of the cancer compared to 1999 where the peak incidence was in the age group 40–65 [2]. The incidence can occur since very young age. Interestingly, the most common histological types of ovarian cancer in 2011 were serous carcinoma followed by mucinous carcinoma and endometrioid carcinoma. This showed a larger variation from the data in 1999 as the two most prevalent histological types were serous and mucinous cystadenocarcinoma [2]. The most common stage of ovarian cancer was local, followed by regional stage.
