Dolph Lundgren's Cancer Battle During 'Aquaman 2' Filming.

Actor Dolph Lundgren revealed that he has been privately battling cancer on and off for the last eight years. Doctors first discovered and removed a cancerous tumor on the actor’s kidney in 2015. Lundgren said six more tumors were discovered in 2020, and more tumors were discovered in the fall of 2021. Lundgren eventually got a second opinion from a doctor in London who discovered that his kidney cancer was mutating more like lung cancer. The new treatment started shrinking his tumors by around 20% and 30% within a three-month period. Lundgren is reprising his roles in "Aquaman and the Lost Kingdom" and "The Expendables 4."
