Types of treatment by timing

Cancer treatment is often a multi-step journey, and the timing of each intervention is carefully planned to maximize success and improve patient outcomes. The foundation of this approach is the primary treatment, which is the main strategy used to eliminate the cancer from the body. Depending on the type and location of the tumour, this primary measure is very frequently surgery, though it can also be another major intervention designed to eradicate the bulk of the disease.

To support the primary treatment, oncologists frequently use therapies timed either before or after the main procedure. When a treatment is administered before the primary plan, it is known as neoadjuvant therapy. A common example of this is giving chemotherapy or radiation first to shrink a large tumour, making it significantly safer and easier for a surgeon to operate on. Conversely, treatment given after the main plan is called adjuvant therapy. An example of this is undergoing radiation or chemotherapy following surgery to mop up any microscopic cancer cells that might have been left behind, which substantially reduces the risk of the disease returning.

In cases where a cancer is advanced and cannot be fully cured, the focus of medical care shifts toward palliative treatment. Rather than aiming for eradication, the goals of palliative care are to control the growth of the cancer, manage pain, and alleviate uncomfortable symptoms. This ensures that the patient maintains the best possible quality of life, focusing on comfort, dignity, and prolonged well-being.
