Can post surgical inflammation/scarring from breast implants cause cancer later on life?

No. Despite decades of research there is no relationship between breast implants and the development of breast cancer.
Very low risk. People have looked at this intensively. There's a very rare and distinctive malignant lymphoma that occurs in this setting. I wouldn't waste time worrying about it. The implants don't cause breast cancer. If other cancers result from the scar formation, which doesn't make sense biologically, they are too uncommon for a risk to be measurable.
