  • 24

    Myelofibrosis

    Myelofibrosis is a rare type of bone marrow cancer where scar tissue gradually replaces the healthy tissue that makes blood cells, leading to serious complications and changes in daily life that require careful management and support.

  • 1

    Myeloid leukaemia

    Myeloid leukaemia is a type of blood cancer that begins in the bone marrow and affects blood cells. It develops rapidly and requires urgent treatment, but newer treatments are helping more people live longer with this condition.

  • 6

    Myeloproliferative neoplasm

    Myeloproliferative neoplasms are rare blood cancers that happen when your bone marrow makes too many blood cells—but with the right treatment, many people can manage these conditions and enjoy a near-normal lifespan.

  • 10

    Myocardial infarction

    A myocardial infarction, commonly known as a heart attack, is a serious medical emergency that occurs when blood flow to part of the heart muscle stops or becomes severely reduced, causing the heart tissue to die from lack of oxygen.

  • 9

    Myocardial ischaemia

    Myocardial ischaemia is a serious condition where your heart muscle doesn’t get enough oxygen-rich blood to work properly. This happens when the arteries that supply blood to your heart become narrowed or blocked, often by a buildup of fatty deposits called plaque.

  • 9

    Myocarditis

    Myocarditis is an inflammation of the heart muscle that can reduce the heart’s ability to pump blood effectively. While the condition affects thousands of people each year, many individuals and even some physicians are unfamiliar with it, making proper diagnosis and treatment essential for recovery.

  • 1

    Myocarditis post infection

    Myocarditis post infection is inflammation of the heart muscle that develops after a viral or other infection. While this condition can be worrying, most people make a very good recovery with proper treatment and care.

  • 2

    Myofascial pain syndrome

    Myofascial pain syndrome is a long-term pain condition affecting muscles and the thin tissue that surrounds them. It causes deep, aching pain that doesn’t go away with rest, often centered around sensitive knots in the muscles called trigger points.

  • 9

    Myopia

    Myopia is a common eye condition affecting millions worldwide, where distant objects appear blurry while close objects remain clear. Understanding this condition and the available treatment options can help protect your vision and reduce the risk of serious eye problems later in life.

  • 0

    Myositis

    Myositis is a rare disease that makes your immune system attack your own muscles, causing chronic inflammation that leads to muscle weakness and fatigue. While there is no cure, treatment can help manage symptoms and improve quality of life.

  • 1

    Myotonia

    Myotonia is a condition where muscles struggle to relax after contracting, causing stiffness and delayed movement. While this disorder can significantly impact daily activities, understanding its various forms and available treatments helps people manage their symptoms and maintain quality of life.

  • 3

    Myotonic dystrophy

    Myotonic dystrophy is a complex inherited condition that affects muscles and many other parts of the body. People with this condition experience progressive muscle weakness, difficulty relaxing muscles after contraction, and a range of other symptoms that can affect the heart, eyes, and other organs.

  • 0

    Myxofibrosarcoma

    Myxofibrosarcoma is a type of cancer that starts in the connective tissue, most commonly appearing as a slow-growing lump in the arms or legs. This cancer primarily affects older adults and has a tendency to return even after treatment, making careful monitoring essential for those diagnosed with this condition.

  • 3

    Myxoid liposarcoma

    Myxoid liposarcoma is a rare cancer that develops in fat cells, most commonly appearing as a slow-growing lump in the legs or arms. Many people carry this condition for years without noticing symptoms, as it typically grows quietly before becoming visible under the skin.
