- CryotherapyCryosurgery involves freezing of the prostate gland under anesthesia to destroy cancer cells. Biopsy proves recurrence after cryotherapy ranges from 14.5% to 38%. Incontinence rate is 4.8% and only 25% of patients could have intercourse after cryosurgery.

- Smoking CessationIt is therefore always in the patients best interest to seek consultation for seeding when the chest tumors are as small as possible. Smoking cessation and regular aerobic exercise conditions the lungs for maximal gas exchange before and after the implants.

- Internal MedicineHe completed his Medical Degree at the University of South Florida College of Medicine (1980) and completed an internal medicine internship at Richland Memorial Hospital at the University of South Carolina. Dr. Doggett's interest in Radiation Oncology led him to complete the residency program at St. Mary's Medical Center in San Francisco (1986) and to complete a Fellowship in Brachytherapy and Hyperthermic Oncology at the City of Hope National Medical Center (1987). Dr. Doggett has since focused his Private Practice in the area of Radiation Oncology and Brachytherapy. Dr. Doggett continues to publish and teach physicians.

- Prostate CancerSeveral genetic analysis tests now exist for prostate cancer. They are performed on the existing specimen so another biopsy is not needed. The DNA from the cancer cells is extracted, sequenced and analyzed. The sequence is compared to the sequences of a library of thousands of patients who underwent sequencing and analysis over ten years ago at various academic institutions. These patients have been closely followed as part of scientific studies and the outcomes of their cancers are known and studied.
- Lung CancerWe have extensive experience in taking care of both prostate and lung cancer cases for decades. Dr. Doggett uses the best approaches to minimize number of visits for treatment with least inconvenience to the patients and their families as well as getting the same results as the large institutions who have much higher overhead with expensive equipment.
- UltrasoundIntraoperative treatment planning uses a high speed computer in the operating room to electronically collect the ultrasound images and automatically calculate the treatment plan with little chance for human induced error. This revolutionary technology was pioneered by Dr. Doggett and is setting the standard for prostate brachytherapy technology. This technology is designed to dramatically increase precision of seed placement, to increase cure rates and decrease complication rates. The system is a platform for technology soon to be introduced including real time virtual needle guidance systems and robotic needle and seed placement systems.
- MRIPreoperative triple phasic or multiparametric MRI is occasionally ordered to evaluate the tumor burden in the prostate. Not all patients require this analysis however. The three phases of this sophisticated MRI are

- Computed TomographyDuring the late 80’s and early 90’s the invention of transrectal ultrasound emerged allowing for improved the evaluation of the prostate. This advancement directly addressed the need for improved volume estimates of the prostate gland. Combined with the developments of template guidance, or precise needle placement of radioactive sources, Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) these technical improvements addressed the issues of the early years and advanced brachytherapy as a viable treatment for prostate cancer.

- Radiation TherapyRequires 5 to 9 weeks of daily radiation therapy. Not effective for aggressive prostate cancers. Effective for prostate cancer cases with low PSA Number. It is, however, a non-invasive therapy.

- DermatologyThe introduction of an electronic brachytherapy delivery system into an existing general dermatology practice is described. Radiobiologic rational for the dose fractionation schedule is detailed.
- LesionsAccurately implanted lesions that receive sufficient radiations will resolve and not return at least 90% of the time. Smaller lesions are easier to sterilize completely and larger lesions may require a second implant to touch up areas that were under dosed at the first seeding.
