Why Some Cancer Drugs Stop Working Cancer treatments have improved greatly. Many drugs now shrink tumors and extend lives. However, for many patients, these drugs eventually stop working. This problem is called drug resistance. It remains one of the biggest challenges in cancer care. Resistance can appear quickly, within weeks. In other cases, it develops […]

Dose-Response Relationships in Cancer Therapy Dose-response relationships describe how the amount of a treatment affects its results in cancer therapy. A higher dose usually increases the effect on cancer cells. However, it also raises the risk of damage to healthy tissue. Doctors use these relationships to choose doses that maximise benefit while limiting harm. Basic […]
EGFR Inhibitors in Cancer Treatment EGFR inhibitors target a key protein that drives the growth of many cancer cells. These drugs block signals that tell cells to divide and survive. As a result, they slow tumour growth in selected patients. However, doctors use them only after testing for specific genetic changes. EGFR stands for epidermal […]

Stereotactic Radiosurgery
Stereotactic Radiosurgery Stereotactic radiosurgery delivers precise radiation to a small target area in the body. Doctors use advanced imaging to guide the beams. Therefore, the treatment focuses energy exactly where it is needed. Healthy tissue around the target receives very little exposure. Patients usually complete the procedure in one session or a few sessions. Specialists […]

Blood Cell Formation and Cancer
Blood Cell Formation and Cancer Blood cell formation, or hematopoiesis, produces all types of blood cells from stem cells in the bone marrow. Healthy stem cells divide and differentiate into red blood cells, white blood cells and platelets. This process remains tightly controlled throughout life. However, genetic changes can disrupt normal development and lead to […]
Occupational Exposure and Cancer Incidence Occupational exposure refers to contact with harmful agents during work. These agents include chemicals, dust, radiation, and certain biological materials. Repeated or prolonged contact can increase the risk of specific cancers. Researchers and health agencies track these patterns to protect workers and guide prevention. Common Workplace Carcinogens Several well-studied substances […]
