Linda has incurable liver cancer and previously battled breast cancer in 2006, cellulitis and lymphedema in her arm in 2007 and secondary pelvic cancer in 2017.
Anne has stage three breast cancer, the most serious being stage four.
Their sister Bernie died of breast cancer in 2013.
Now Coleen has said she is considering a double mastectomy.
Appearing on a video call from her home, she told Andrea McLean, Judi Love and Denise Welch, that she shared her grief at not being able to visit Linda and Anne.
Coleen remembers wanting to get in the car and go straight to Blackpool, but couldn’t because they were at ‘incredibly high risk’ of coronavirus now that they were undergoing chemotherapy.
“They have terrible days where they are incredibly sick,” she said, “I cannot go and see them because they are extremely at risk.”
She added that they were being looked after by other sisters Maureen, living with Anne, and Denise, living with Linda.
As they spoke more on the subject Coleen couldn’t hold back tears and Andrea called for a commercial break.
Linda recently appeared on Good Morning Britain, telling co-hosts Ben Shephard and Kate Garraway that she now sees “Bernie looking back. [her] in the miror. “
When asked how their family responded to their joint diagnoses, Linda explained, “It’s really hard and I don’t think we could have done it without our family so close. ”
Linda added: “I had chemotherapy in 2006 and I used a cold cap, which they put this cap on and freeze it and it freezes the follicles in your hair.
“I managed to keep my hair a bit on last time, but this time it didn’t have a fitted cold cap, oddly enough, that’s why my hair fell out.
“I was traumatized by it. I feel vain to say that the worst part is that I have no hair, but it was traumatic for me. “
