Kate Middleton's 'brutal' side effects of cancer treatment laid bare

Princess Kate is believed to be suffering a great deal of discomfort as a result of her ongoing treatment from cancer.

According to RadarOnline, a source told National Enquirer the Princess of Wales is making desperate efforts to keep a brave face in front of her young children; however, the journey hasn’t been co-operative.

As per reports, she is reeling from side effects of preventative chemotherapy, including exhaustion, nausea, and more.

"Kate and William are going through hell behind palace walls," a high-level royal courtier told the outlet.

They went on to note “it’s becoming more and more difficult” to hide her suffering from Prince George, 10, Princess Charlotte, 9, and Prince Louis, 6.

New York-based Dr. Stuart Fischer, who has not personally treated Kate, corroborated the tipster’s explanation of the side effects of the treatment, admitting it's a "destructive process" because the skin, hair, lining of the intestines and bone marrow are all affected.

"Cancer is a physical and emotional burden unlike many other conditions,” he claimed.

For the unversed, the 42-year-old princess unveiled her diagnosis with cancer via a video appearance in March.

The shock announcement followed Kate’s prolonged absence from the public eye since the beginning of the year as she underwent recovery from a major abdominal surgery.
