What being a breast cancer researcher has taught me.

Hello! My name is Ashkan Sadri and I’m a Masters candidate in Dr. Alison Allan’s lab in the Department of Anatomy and Cell Biology at Western University, just coming to the conclusion of my thesis research.

When I engage in casual conversation, the topic of graduate school and breast cancer research often arise. By far, the most common question I’m asked is: “Does a cure exist?” And to that, it’s hard to give a simple answer.

Ashkan Sadri, BCSC ResearcherWhat is difficult to communicate to those outside of the cancer research field is that, due to the complexity of cancer, it is unlikely a single cure exists. Over the past two years, the basis of my research has been to investigate whether the factors produced by different organs in the body such as bones and the lungs can promote a rare, stem-like population of breast cancer cells with heightened capacity to form metastatic tumors in these organs. Our research findings turned out to challenge our predictions, providing an important means for thinking outside of the box. Not only were the stem-like traits of breast cancer cells not promoted when exposed to the lung microenvironment, they were actually reduced. We have gone on to identify a novel subpopulation of breast cancer cells that may potentially be involved in metastasis to the lung, using pathways that are distinct from the original cancer stem cell model. Thus, when asked, about a “cure to cancer”, it’s important to consider the complex nature of cancer biology and the many unknowns that exist, emphasizing the need for valuable research to be conducted.

When confronted with a treatment, breast cancer cells often find alternative means to progress along their path. Cancer treatments are effective in blocking key pathways, but alternative routes exist that the cancer cells can utilize. This is why supporting breast cancer research is vital. Learning about different mechanisms that drive tumour development are necessary to finally get breast cancer under control. By supporting breast cancer research, researchers are able to make a global impact when it comes to gaining ground on cancer.

Thank you to BCSC for your trainee support!
