Urologic Oncology in Lake Mary, Florida (FL)

More potent and effective treatments for cancer are available to your doctor than ever before. Major advances in chemotherapy, radiation therapy, and surgery make these traditional cancer treatments more effective than ever. Additionally, cutting edge research has yielded an expanding array of new treatments to complement traditional cancer treatments. More accurate diagnostics enables your doctor to detect cancer earlier than in previous generations.

Traditional Oncology Procedures

Chemotherapy uses drugs to kill cancer cells. The most common types of urological cancers treated with chemotherapy include:
  • prostate cancer
  • bladder cancer
  • kidney cancer
  • testicular cancer
Urethral cancer and penile cancer may also respond well to chemotherapy.

Radiation therapy can be used in conjunction with other therapies. External radiation therapy uses radiation from a machine outside the body to kill cancer cells. Internal radiation therapy is a procedure in which your doctor places a radioactive substance into or near the cancer and seals it inside seeds, wires, needles or catheters.

Surgery is a tool oncologists use to physically remove cancer-infected areas. Your doctor may perform traditional open surgery in which a large incision is made to access and remove cancerous tissue. Laparoscopy is a newer, less invasive surgery in which smaller incisions are made and tiny tools are used to remove cancer cells. Your surgeon may be specially trained in the da Vinci system which uses robotic arms to perform fine surgical cuts and procedures.

Newer Oncology Procedures

Newer cancer treatments that are being developed to treat some kinds of cancer and precancerous conditions include cryosurgery, which uses cold to target cancer cells, and radiofrequency ablation which uses heat to target cancer cells. Though still under study, these methods offer some shorter recovery times and fewer side effects.

Stem cell transplantation stimulates the body’s own immune response to combat cancer. Stem cell transplantation uses immature blood cells to stimulate healthy blood cell growth which may be helpful in the treatment of aggressive testicular cancer.

New drugs are being developed to target specific characteristics of cancer cells. Sorafenib, sunitinib, and everolimus are new drugs which directly target proteins or other molecules that fuel cancer cell growth in kidney cancer.

Talk to your doctor about which treatments are right for you.
