Cancer is the second leading cause of death globally, claiming nearly 10 million lives in 2021. In 2025, around 2 million Americans are expected to be diagnosed, according to the American Cancer Society.

This disease can affect anyone, regardless of lifestyle, age, or background. While factors like smoking, alcohol, and poor diet increase risk, even healthy individuals can be blindsided by cancer.

Early detection is critical. One often-overlooked symptom is night sweats or hot flashes, which may signal cancer-related fever or hormonal shifts due to the disease or treatments like hormone therapy for breast or prostate cancer.

Insomnia is another symptom linked to cancer. Though common and caused by various factors, persistent insomnia may indicate an underlying issue.

According to Cancer Research UK, being aware of unusual changes and seeking medical advice early increases the chance of successful treatment.

Don’t ignore persistent symptoms—early action can save lives.
