Cancer treatments, particularly certain chemotherapeutic agents and targeted therapies, can lead to increased blood pressure as a side effect. For instance, drugs such as angiogenesis inhibitors (e.g., bevacizumab) disrupt blood vessel growth, which can lead to hypertension. Similarly, some hormonal therapies used in breast and prostate cancers may also elevate blood pressure. Close monitoring and management of blood pressure are essential during cancer treatment to mitigate cardiovascular risks.
