Disease Comparison

Overview

Synovitis

Synovitis is inflammation of the synovial lining of a joint, which can cause swelling, pain, warmth, stiffness, and reduced movement. It may develop after an injury or repeated joint stress, or as part of infection, autoimmune arthritis, crystal disease, or another inflammatory condition. Treatment and evaluation depend on the underlying cause.

Endometrial Cancer

Endometrial cancer is a cancer that begins in the lining of the uterus, called the endometrium. It is one of the most common cancers of the female reproductive system. Abnormal cells can grow uncontrollably and may invade nearby tissues or spread to other parts of the body. Abnormal vaginal bleeding, particularly bleeding after menopause, is an important symptom that should be evaluated.

Diagnosis

Synovitis

Diagnosis of synovitis is based on symptoms and examination of the affected joint, including assessment of swelling, warmth, tenderness, stiffness, and movement. Imaging such as X-rays, ultrasound, or MRI may help identify structural or inflammatory changes. Blood tests may be useful when an inflammatory disease is suspected. Joint-fluid analysis may be performed when infection or crystal disease needs to be investigated.

Endometrial Cancer

Diagnosis usually begins with evaluation of abnormal vaginal bleeding or other symptoms and a pelvic examination. Transvaginal ultrasound may be used to assess the thickness and appearance of the endometrium. A definitive diagnosis generally requires sampling the uterine lining, usually with an endometrial biopsy. Hysteroscopy or dilation and curettage may be used when additional tissue evaluation is needed. Imaging can help determine whether cancer has spread.

Prevention

Synovitis

Prevention of synovitis depends on its underlying cause. Protecting joints from repetitive strain, using appropriate techniques during physical activity, and allowing adequate recovery after strenuous activity may reduce irritation. Prompt and appropriate treatment of joint injuries and infections can also help. People with inflammatory or metabolic conditions should follow their treatment plans and maintain healthy activity levels.

Endometrial Cancer

Endometrial cancer cannot always be prevented, but maintaining a healthy weight, staying physically active, and managing conditions such as diabetes may reduce risk. Hormone therapy should be used according to medical advice, with appropriate consideration of whether estrogen is given with progesterone. People with Lynch syndrome or a strong family history should discuss appropriate risk assessment and screening or preventive options with a healthcare professional.

Risk Factors

Synovitis

Risk depends on the underlying cause of synovitis. Repetitive joint stress, previous joint injuries, inflammatory arthritis, infection, crystal disease, and some metabolic disorders can increase the likelihood of inflammation. People with conditions that affect the joints or immune system may therefore have a greater risk, while the specific risk factors vary according to the type and cause of synovitis.

Endometrial Cancer

Risk factors include increasing age, obesity, prolonged estrogen exposure, early menstruation, late menopause, never having been pregnant, certain hormone therapies, diabetes, and a family history of endometrial or colorectal cancer. Lynch syndrome and some other inherited genetic conditions can substantially increase risk. Risk varies among individuals and may depend on the combination of hormonal, metabolic, and genetic factors.
