Well written PONS. My thoughts exactly.
The Pre-Med answered fairly well to the highschooler. He/she did forget one major tier: Surgical Oncology.
Oncology is driven by three drivers:
Medical Oncologist
Radiation Oncologist
Surgical Oncologist
All are oncologists. The Med Oncologist prescribes the Chemo but so much more as well: runs the clinical trials, determines the staging of the cancer, diagnosis as to whether the cancer is benign, neo-adjuvant, adjuvant, metastatic, palliation, etc.
The Rad Onc administers the radiation but also much more. Lots of neat toys in a Rad Onc Center. Check them out. Visit one. Pretty futuristic stuff.
The Surgical Oncologist works with the Med Oncologist once the Med Oncologist finds the tumor, and the Surg Oncologist takes out what they can, then informs the Med Oncologist what was removed, clean margins, what was solid, what was not, and what other surrounding areas needed to be sacrificed (breast lump vs breast mastectomy). After surgery and radiation, it's back to the Med Oncologist to determine whether chemo should be administered which often is, enrolled in a clinical study or just administer palliative tx. the Med Onc has the really cool job b/c they are part of the last stage of life. Dying is part of life. While some would feel it is depressing field, I disagree. It is a great career when you think about being there for patients for their last stage in life.
Oncology is a very profitable field, and each division makes a different amount based on their modality of tx. The Med Onc makes money for diagnosis, office visits, quality of life issues, instruction, plus the actual administration of chemo and other meds via IV in their office. The medication is profitable to the Med Onc to the toon of: 6% plus ASP (Average Sales Price) based on CMS tables as to the chemo prescribed. Meaning, the Med Oncologist is at an advantage to prescribe branded chemo products (non-generic) b/c they are the pricier ones. So, if a patient needs chemo, the Med Onc MIGHT be motivated to Rx a branded chemo instead of a generic b/c they will make 6% plus ASP on that drug from the distributor. If the drug chosen is generic, then the Med Onc makes peanuts.
The surgical oncologist only gets paid when she/he yanks something out.
The Rad Onc gets paid when she/he administers Radiation.
Notice how the Med Onc calls the shots. It's up to the Rad Onc and Surg Onc to grovel, nay, network w/ their local Med Oncs for referrals. No ticket = no laundry
I see it all the time and I love this part of medicine.
