The tables below give information about the countries with the highest rates, incidence and mortality from ovarian cancer.

Ovarian cancer incidence (cases)

China, India and the US had the highest number of ovarian cancer cases in 2022.

The following table shows the 10 countries with the highest ovarian cancer incidence. We have also included the age-standardised rate (ASR)* for each of these countries.

Rank	Country	New cases 2022	ASR/100,000
	World	324,603	6.7
1	China	61,060	5.7
2	India	47,333	6.6
3	US	21,179	7.3
4	Indonesia	15,130	9.8
5	Russia	14,606	11.5
6	Japan	10,693	8.7
7	Brazil	7,710	5.1
8	Germany	7,547	7.0
9	Philippines	6,453	11.7
10	UK	6,390	9.2

Ovarian cancer age-standardised rates

*Age-standardised rates (ASR) are a summary measure of the rate of disease that a population would have if it had a standard age structure. Standardisation is necessary when comparing populations that differ with respect to age because age has a powerful influence on the risk of developing/dying from cancer.

It is important to note that some countries have a high ASR but a low total number of cases, while others have a low ASR but a high number of cases. This is because ASRs are reported per 100,000 people. So, for example, an ASR of 10 in a population of 100,000 = 10 cases of cancer, but an ASR of 1 in a population of 10 million = 100 cases.

The following table gives the top 5 countries by ASR for ovarian cancer incidence.

Country	New cases 2022	ASR
Latvia	298	15.3
Samoa	12	14.2
Brunei	33	13.2
Lithuania	366	12.8
Poland	4,678	12.2
