SUBSTANCE: composition of 5,10,15,20-tetrakis(N-methyl-3'-pyridyl)chlorine and 5,10,15,20-tetrakis(N-methyl-3'-pyridyl)bacteriochlorine is administered into a tumour tissue as a photosensitiser in an amount of 0.5-10mg per 1g of tumour tissue depending on a degree of tumour differentiation. The laser exposure starts 20-40 minutes later at wave length 760-762 nm. The cytological examination follows 6-7 days later, and if observing signs of persistent tumour growth, the presented therapeutic session is repeated.
