drink a lot of alcohol – your risk can increase with the amount of alcohol you drink.are overweight – particularly if you've been through the menopause (you can use the BMI healthy weight calculator to find out whether you're overweight or obese).have had a type of benign (non-cancerous) breast disease before – certain types of benign breast disease may be associated with an increased risk of breast cancer, but this is only seen in a very small number of women.have close relatives with breast cancer.are older – the risk of developing breast cancer increases with age.In terms of risk factors, you're more likely to develop breast cancer if you: There are no known causes that lead to a specific type of breast cancer. Some women appear to be more at risk of developing breast cancer, but not specifically Paget's disease. The cause of Paget's disease of the nipple is unknown. This is where the cancerous cells are contained in 1 or more areas of the breast and have not spread. However, most women with Paget's disease who do not have a lump have non-invasive cancer. Invasive cancer is where cancerous cells invade the surrounding breast tissue. Some women with Paget's disease have invasive breast cancer but do not have a lump. In 9 out of 10 cases this is an invasive breast cancer. However, you should still have it checked by a doctor.Īround half of all women diagnosed with Paget's disease of the nipple have a lump behind the nipple. If you're experiencing itchiness, burning or bleeding but the nipple looks normal and is not red or scaly, it's unlikely to be Paget's disease of the nipple. If you scratch it, or if it's left untreated, it can bleed, become ulcerated or scab over. The rash is often similar in appearance to other skin conditions, such as eczema or psoriasis. The affected skin is often sore and inflamed, and it can be itchy or cause a burning sensation. It appears as a red, scaly rash on the skin of the nipple and areola. Paget's disease of the nipple always starts in the nipple and may extend to the areola. The term Paget's disease of the nipple is used to distinguish the condition from Paget's disease of the bone (where bones become weak and deformed). It can also affect men, but this is extremely rare. It's usually a sign of breast cancer in the tissue behind the nipple.Ībout 1 to 4% of women with breast cancer have Paget's disease of the nipple. It causes eczema-like changes to the skin of the nipple and the area of darker skin surrounding the nipple (areola). Paget's disease of the nipple, also known as Paget's disease of the breast, is a rare condition associated with breast cancer.
