Michael Lohan — father of Lindsay Lohan — underwent a most cancers process right now on his hand … TMZ has realized.

Michael tells TMZ … he is been combating pores and skin most cancers for some time, being recognized with squamous cell carcinoma about 4 years in the past and “not too long ago had a suspicious lesion on my hand” that prompted docs to do a biopsy.

Issues modified Tuesday night time when he acquired a name relating to the biopsy and that he wanted to get the patch eliminated ASAP — and Wednesday, that is precisely what occurred.

He tells us the most cancers had “deep roots” and wanted lots of digging, however we’re instructed they fortunately had been capable of get all of it out.

Michael admits the kind of most cancers he has is “aggressive” and he is continuously monitoring it … including it seemingly will return sooner or later.

Lindsay’s father posted about his new scar on Instagram Wednesday, writing, “A scar means the damage is over, the wound is closed, you endured the ache, and God has healed you.”

BTW, we’re instructed his son, Michael Jr., was the one one who knew about his medical scenario — and Michael tells us he did not need Lindsay to fret or have an effect on her work, which is why she was unaware.

As you understand, Lindsay gave followers a giant shock when she appeared on the NYC premiere of the brand new “Imply Women” flick earlier this week, smiling alongside Tina Fey, one in all her costars from the 2004 model.
