Lower blood cell production

Your bone marrow's ability to make blood cells might decrease.

• Anemia. You may not have enough healthy red blood cells to carry oxygen to your tissues, which can leave you feeling tired or short of breath.
• Bleeding. You may not have enough platelets — a blood cell that plays an important role in forming blood clots — to help prevent bleeding when you're injured.
• Infections. You may have fewer white blood cells to protect your body from infections.
