2. Flu-like symptoms
As mentioned, leukemia weakens the immune system. As a result, people who are affected by this form of cancer are more susceptible to viruses and bacteria, which can lead to the development of flu-like symptoms. These symptoms can include fever, chills, night sweats, coughing, sore throats, and muscle aches and pains. Additionally, since the white blood cells are suppressed, they are not able to effectively fight off infections, which can make these symptoms may become commonplace, and they can last for a prolonged period of time. Also, patients are more prone to developing a variety of illnesses, including pneumonia, the common cold, the flu, and various other ailments.
