Overview

Rheumatoid Arthritis
Rheumatoid arthritis is a chronic autoimmune disease that primarily causes inflammation of the joints. The immune system mistakenly attacks tissues around the joints, leading to pain, swelling, stiffness and reduced movement. It often affects the hands, wrists and feet symmetrically, but can involve other joints and organs. Persistent inflammation can damage joints and affect overall health.
Breast Cancer
Breast cancer develops when abnormal breast cells grow without normal control. Common invasive types begin in the milk ducts or milk-producing lobules and extend into surrounding tissue. It occurs mainly in women but can also affect men. Possible changes include a lump, thickening, altered breast shape, or nipple discharge; some cancers cause no obvious symptoms.

Diagnosis

Rheumatoid Arthritis
Diagnosis is based on symptoms, physical examination, blood tests and imaging. Blood tests may measure rheumatoid factor and anti-CCP antibodies and assess inflammation. X-rays, ultrasound or MRI can show joint inflammation or damage. No single test confirms rheumatoid arthritis in every person, so the overall clinical picture is considered.
Breast Cancer
Screening looks for cancer before symptoms appear; diagnostic evaluation investigates symptoms or an abnormal screening result. Evaluation may include examination, diagnostic mammography, ultrasound, or MRI when appropriate. A biopsy examines tissue to confirm cancer. After confirmation, tests assess tumor characteristics, including hormone receptors and HER2, and determine the extent of disease.

Prevention

Rheumatoid Arthritis
Rheumatoid arthritis cannot always be prevented because genetic and immune factors contribute to its development. Avoiding tobacco use is an important way to reduce risk. Maintaining a healthy weight and addressing other modifiable health factors may also be beneficial. Early medical evaluation of persistent joint swelling and stiffness allows appropriate treatment to begin before significant joint damage develops.
Breast Cancer
Risk reduction cannot guarantee prevention. Limiting alcohol, maintaining a healthy weight, and being physically active may reduce risk. People with a strong family history or known inherited susceptibility can discuss genetic assessment and appropriate risk-reduction options with a healthcare professional. Screening is intended to detect cancer early; it does not prevent cancer from developing.

Risk Factors

Rheumatoid Arthritis
Risk factors include having certain genetic traits, being female, increasing age and having a family history of rheumatoid arthritis. Smoking is an important modifiable risk factor. Obesity and some environmental exposures may also contribute. The disease can occur in people without any known risk factor.
Breast Cancer
Risk increases with age. Other factors include a personal history of breast cancer or certain breast conditions, family history, inherited susceptibility, and dense breasts. Hormonal and reproductive history can influence risk. Alcohol use, excess weight after menopause, and physical inactivity are also associated with increased risk. Having a risk factor does not mean cancer will develop.
