1. Imaging Tests: Techniques such as CT scans, MRIs, PET scans, and X-rays help visualize the tumor and surrounding tissues to assess size, shape, and location. 2. Blood Tests: Tests like Complete Blood Count (CBC) and tumor markers (e.g., PSA for prostate cancer, CA-125 for ovarian cancer) provide information on the presence and progression of cancer. 3. Biopsies: Tissue biopsies offer detailed information about the cancer cells, their type, and genetic mutations, aiding in personalized treatment approaches. 4. Physical Exams: Regular physical check-ups help in identifying new symptoms and assessing overall health. 5. Molecular Testing: Advanced genetic and molecular tests identify specific mutations that can be targeted by precision medicine.
