Amid his divorce from wife Christina El Moussa, “Flip or Flop” star Tarek El Moussa has opened up further about the health problems that have dogged him, revealing that he battled testicular cancer as well as thyroid cancer. While El Moussa’s battle with thyroid cancer has been well-documented, the reality TV star said that he was reluctant to reveal the testicular cancer as “it was more of a personal thing.” Tarek was diagnosed with thyroid cancer after a registered nurse emailed the show’s production company in 2013 to suggest that Moussa get a medical checkup for a large nodule on his thyroid, according to The Independent.
