1. The foremost step in improving cancer diagnosis is its early detection.
  2. Following screening protocols is the best method of early diagnosis.
  3. Fine needle aspiration of lumps which can be felt on the body is done directly by a pathologist. For internal lesions a fine needle aspiration under guidance of a radiologist can be done by a pathologist and the slide seen under the microscope by a pathologist.
  4. An ultrasonogram in case of suspicious symptoms and getting it done  annually after the age of 40 would help detect changes in internal organs.
  5. Relevant tumor markers in high risk cases.
  6. Tissue biopsies maybe required in certain cases. A pathologist shall guide you on this.
  7. Liquid biopsies ( blood sample for tumor cell detection) are being researched extensively, however as of date are not the standard diagnostic method. The problems are lack of knowledge of the frequency of tumor cells being shed in the blood, standardization and lack of knowledge of sensitivity of these tests when applied to various cancers. The utility in the present day is more towards monitoring therapy.
