A nurse has issued a warning that three symptoms of kidney cancer could manifest overnight while you’re asleep.

Hazel Jackson, the lead healthcare professional nurse at Kidney Cancer UK, cautioned that persistent night sweats, nocturnal pain, and extreme fatigue might indicate the presence of the disease.

Speaking to Surrey Live, she explained that consistently waking up drenched could be a sign that the body is battling cancer. “Waking up drenched, with sweat soaking through your sleepwear and bedding, can be alarming.

“These episodes may be the body’s response to fighting cancer. While night sweats can result from hormonal changes or a flu, if they persist and are accompanied by other symptoms, it’s time to speak with a doctor.”

Hazel also highlighted that nocturnal pain could be a symptom, particularly if it’s located in a specific area. She elaborated: “Kidney cancer pain typically occurs in the lower back or side (flank) and is a constant ache.

This pain can become more noticeable at night while lying down, as the body’s position may put added pressure on the area.”, reports Surrey Live.

Moreover, while extreme fatigue can have multiple causes, Hazel suggested it could be a red flag if you’ve had a good night’s sleep but still feel tired in the morning.

She advised: “Feeling exhausted despite a full night’s sleep? If rest doesn’t improve your energy levels, and this fatigue appears alongside other symptoms, it’s worth reaching out to your GP.”

Charities like Kidney Cancer UK highlight that kidney cancer ranks as the eighth most common cancer in the UK, with Cancer Research UK noting that about 13,000 new cases are diagnosed annually.

The NHS warns that “no obvious signs of kidney cancer” exist and it’s often identified incidentally during tests for other issues.

They list primary symptoms as blood in the urine, a lump or swelling in the back beneath the ribs, or in the neck. Additional symptoms may include persistent pain between the ribs or waist, unexpected loss of appetite, and unexplained weight loss.

Echoing Kidney Cancer UK, the NHS also lists fatigue, night sweats, and a high temperature as potential indicators of the disease. Malcolm Packer, CEO of the charity, also told the Daily Express that persistent high blood pressure could be a red flag.

He explained: “The kidneys play a vital role in regulating blood pressure, and tumours can disrupt this function. Persistent hypertension, especially when coupled with other symptoms, should prompt individuals to seek medical attention and consider kidney cancer screening.”
