The Entourage star, Constance Zimmer, has sent her boat to recovery! 

On Monday, October 5th, the actress has lifted the lid from her secret cancer battle as the world kicked off the Pinktober.

Taking to her Instagram account the cancer-stricken artist shared, "October is #breastcancerawarenessmonth and I never thought I’d be honoring it with my own story."

She continued explaining her emotional journey, as she revealed, "On March 13th when I was away from home – I heard these words from my doctor over Zoom: ‘You have DCIS, also refereed to as Stage 0 breast cancer."

"The silence was deafening," she added.

Constance further revealed her cancer journey as she described the one as, "biggest secret [she’s] ever held."

She only confided her health struggles in those close to her, including daughter Colette and husband Russ Lamoureux, who was the first call she made post-diagnosis.

The 55-year-old American actress also noted that her diagnosis has also affected her mental peace as her sessions with the doctors have been began on regular basis.

However, she later announced that she is officially cancer-free following a private battle with Stage 0 breast cancer (Ductal Carcinoma In Situ, or DCIS).

Diagnosed on March 13, 2026, she managed her treatment covertly while balancing a public press tour for her Emmy-nominated role in the FX series Love Story.

To manage severe perimenopausal symptoms and support her overall well-being, Constance adapted her dietary and health regimen.

Pescatarian diet

Constance Zimmer explicitly changed her diet to a pescatarian plan, focusing heavily on plant-based foods alongside fish for lean protein.

Hormone & vitamin support

Alongside her dietary adjustments, she follows a tailored Hormone Replacement Therapy (HRT) routine involving a hormone patch, progesterone, and testosterone, balanced by an increased intake of Vitamin D.

Historical lifestyle habits

Long known for practicing moderation rather than extreme restriction, her baseline routine has historically included regular Pilates reformer workouts, ensuring 8 hours of sleep, and dedicating occasional days to meatless eating.
