I am assuming that you had breast implants for augmentation (size enhancement) , and not for reconstruction (after mastectomy etc).
Breast implants, especially the silicone gel variety used in the 1980's and 1990's, were known to rupture and leak. Currently, saline filled implants are widely used in the USA, and newer materials are undergoing tests.
Your concern is whether the strong hug soon after surgery may have caused trauma, and possible leak/rupture of the implant, with subsequent pain. It is difficult to say with certainty if this is indeed the case.
Your right breast has been hurting for seven months now. Did you undergo any tests during this time (prior to last weeks mammogram)? Was any imaging done after the incident in the church?
Have you got the result of the biopsy? Do let me know. All the best.
The incidence of breast cancer has not been proven to increase in women who have undergone implants.
What does your breast specialist have to say about this?
This could be scar tissue, but only a biopsy can confirm it for sure.
If it is scar tissue, it is removed surgically or excised by your breast surgeon.
You could try some warm compresses, breast massage and pain relief medications till then.
