Explaining Cancer Types in ‘Demystifying the Darkness’

In the latest installment of her poignant and educational CURE vlog series, "Demystifying the Darkness," Dr. Susan MacDonald continues her mission to strip away the clinical intimidation of an oncology diagnosis. MacDonald, a practicing urologist who is herself navigating the complexities of living with stage 4 breast cancer, brings a unique dual perspective to the screen: the expertise of a surgeon combined with the lived experience of a patient.

In this episode, MacDonald tackles a fundamental question that often overwhelms the newly diagnosed: Where exactly can cancer occur, and how do doctors categorize it? Her answer is as straightforward as it is sobering: "Where can you get cancer? Anywhere."

To help viewers navigate the vast landscape of oncology, MacDonald breaks the disease down into two primary categories: soft tissue cancers and blood cancers. Soft tissue cancers, she explains, encompass the "solid" tumors most people are familiar with. These include carcinomas and sarcomas that take root in the body’s organs and connective tissues. In contrast, blood cancers such as leukemia and lymphoma affect the body’s hematologic and lymphatic systems, circulating through the body rather than forming a single, localized mass.

MacDonald also addresses the frequency of certain diagnoses, helping to contextualize why some cancers dominate public conversation while others remain shrouded in mystery. She identifies the "common" cancers that form the backbone of public health screenings and awareness campaigns: breast, prostate, lung, colorectal and skin cancers. These are the diagnoses that many families have encountered due to their high prevalence in the general population.

However, she also shines a light on the rarer side of the spectrum. From bone and brain cancers to rare ocular tumors of the eye, MacDonald acknowledges the "uncommon" variations that, while less frequent, present unique challenges for patients and researchers alike.

By categorizing these diseases with clinical clarity, MacDonald aims to reduce the darkness of the unknown. Her vlog serves as a reminder that while cancer can appear anywhere, understanding its origins and its type is the first step toward reclaiming agency in the face of a daunting diagnosis.
