World class doctors arrive to talk about gynaecologic cancers

- 02 August 2019

Endometrial cancer (cancer of the lining of the womb) is the most common gynaecological cancer in the world.

Gynaecological Oncologist Dr Ai Ling Tan from Auckland met with Professor Karen Lu from MD Anderson Clinical Cancer Centre the United States in Taupō on Thursday to discuss the causes, factors and effects of the ‘on-the-rise’ cancer.

Prof Lu was the invited speaker at the Australian Society Gynaecologic Oncologists (ASGO) held at the Hilton Lake Taupō [4-7 July].

Professor Karen Lu said endometrial cancers are on the rise due to the increase in obesity worldwide. A study held in the US showed the majority of overweight or obese women aren’t aware of the link between obesity and cancer, let alone obesity and uterine cancer.

Endometrial cancer is caused by an increase in estrogen, driving the cells in the womb to grow and therefore increasing the risk of cancer developing.

Lu said the bottom line is, obesity can increase the risk of breast and uterine cancer because fat cells increase the amount of estrogen that is made.

She said increasing exercise, improving your diet and losing weight will decrease the risk of not only endometrial cancers but other cancers.

Empowering women with information whether they’re in Taupō or anywhere in the world means they have a choice to make some changes to decrease their risk.

Women’s risk of gynaecological cancers can be further elevated by having a faulty gene. These are typically inherited, being passed on by either parent. Lynch syndrome is a condition where faulty genes increase the risk of endometrial cancers.

Two genes that women may have heard of is BRCA1 and BRCA2 which increases their risk of ovarian and breast cancers.

“When a woman finds out she has a faulty BRCA 1 or 2 gene, they will be recommended risk management options.

“Unfortunately, there is no surveillance that improves the detection of ovarian cancer so they will be offered risk-reducing surgery (taking both tubes and ovaries out). However, they don’t need to feel like they need to have surgery immediately.

“It’s best to be thoughtful, think about the timing, implications and the role of hormone replacement,” Lu said.

It’s worth noting that men can also have similar faulty genes that increase their risk of prostate and breast cancer (BRCA1/2) and colon cancer (Lynch Syndrome).

If women (or men) in Taupō are concerned, gather information on their family cancer history and have a discussion with their general practitioners (GP). Sometimes a referral to a genetic counsellor is required.

Dr Ai Ling Tan said GP’s in Taupō can refer to Genetic Health Service (Northern Hub) in Auckland. Patients can also be referred to a private service – NZ Family Cancer Service.
