How fast does cancer progress?

Scientists have found that for most breast and bowel cancers, the tumours begin to grow around ten years before they’re detected. And for prostate cancer, tumours can be many decades old. “They’ve estimated that one tumour was 40 years old. Sometimes the growth can be really slow,” says Graham.

Do cancer tumors grow in size?

Cancerous tumours normally first develop in one site – the primary tumour. However, to get larger, a tumour has to develop a blood supply to obtain oxygen and nourishment for the new and dividing cells.
