Polychromatic light (480-3400nm) similar to the terrestrial solar spectrum without its UV component in post-surgical immunorehabilitation of breast cancer patients.

To this day, two methods of phototherapy (PT) have been successfully used in post-surgical immunorehabilitation of patients with breast cancer (BC): intravenous laser irradiation of the patients' blood and reinfusion of lympholeukosuspension of BC patients after single irradiation with HeNe laser. The objective of this pilot experimental study was to verify the effectiveness of the percutaneous use of polychromatic visible light combined with polychromatic infrared (pVIS+pIR) radiation similar to the major components of natural solar spectrum in post-surgical management of BC patients. Patients with BC (adenocarcinoma) of I-II stages, n=19 who had undergone mastectomy, were divided into 2 groups.

Regulatory systemic effect of postsurgical polychromatic light (480-3400 nm) irradiation of breast cancer patients on the proliferation of tumor and normal cells in vitro.

Objective: The aim of this work was to study the effect of phototherapy (PT) with percutaneous exposures to polychromatic visible and IR light (pVIS + pIR) on breast cancer (BC) patients at the early postmastectomy period, on the growth-promoting (GP) properties of their blood serum, by evaluating its capability to support proliferation of normal and tumor human cells in vitro.

Material And Methods: After mastectomy, one group of patients was treated daily for 1 week on the sacral area with pVIS + pIR light (480-3400 nm, 40 mW/cm(2), 95% polarization, 24 J/cm(2)). The second group used as a control was sham irradiated.
