Abstract: The present invention relates to the use of phytocannabinoids in the treatment of cancer. More particularly it relates to the use of phytocannabinoids in the treatment of tumour cell invasion and cell migration or metastases. Cancers, where invasion and cell migration plays a key role in prognosis include brain tumours, more particularly gliomas, and most particularly Glioblastoma multiforme (GBM) and breast cancers. The phytocannabinoids tetrahydrocannabivarin (THCV) and cannabidivarin (CBDV) alone or in combination with each other and/or other phytocannabinoids, particularly cannabidiol (CBD), tetrahydrocannabinol (THC) and cannabigerol (CBG) or their respective acids are of particular use.
