Which statement is true regarding the biopsies related to cancer?

The statement that biopsies can provide initial diagnosis and guidance for treatment is true because biopsies involve the removal of a small amount of tissue for examination, which can reveal whether cancer cells are present. This process is crucial for accurately diagnosing cancer and determining its type and grade. The histological examination of the biopsy sample helps healthcare professionals understand the characteristics of the cancer, including how aggressive it might be, which in turn informs treatment decisions. Treatment plans—such as surgery, chemotherapy, or radiation—are often developed based on the results of the biopsy.

Additionally, while other options may contain elements of truth regarding cancer diagnosis and management, they do not accurately represent the role of biopsy in the context of cancer evaluation. For instance, biopsies may be performed even when cancer is suspected but not yet confirmed. They are also often essential for diagnosis since many imaging modalities cannot provide definitive information on cell types and disease pathology on their own. Furthermore, while there is a concern about the potential for metastasis, biopsies are generally considered safe and are carefully performed to minimize such risks. Thus, the primary purpose of a biopsy is to provide a reliable basis for diagnosis and treatment planning.
