After being diagnosed with a rare and deadly form of malignant melanoma - acral lentiginous melanoma - Dr George McGavin embarks on a highly emotional and deeply personal journey as he goes through treatment for his cancer. George’s treatment is targeted drug therapy, using drugs approved for use by the NHS only weeks before his diagnosis.
