Burning breast pain

So I came off birth control back in November towards the end of the month. December was my first month without it. All cycles have still been relatively normal and timely. However, about three weeks ago I developed this burning pain in my left breast. It’s not constant and only comes when it’s hit a certain way and in the right spot. Example: when my 7 year old hugs me, he hits the spot and it’s so painful. It literally feels like it’s burning but there’s no actual heat to it. Should I be worried it’s breast cancer or can this be related to coming off the hormones from birth control?
