Mood swings in cancer patients can be attributed to a variety of factors. The emotional and psychological toll of a cancer diagnosis itself is significant. The stress and anxiety surrounding treatment plans, prognosis, and the impact on daily life can cause fluctuations in mood. Additionally, certain cancer treatments, such as chemotherapy and radiation, can affect the brain's chemistry, leading to mood changes. Physical symptoms like pain, fatigue, and sleep disturbances also contribute to emotional instability.
