Discovering a lump in the breast is one of the most anxiety-inducing experiences a woman can have. The instinct to worry is understandable. But it is important to know that 60 to 80% of all breast lumps are benign, meaning non-cancerous, according to multiple studies across South Asian populations.<\/p>\n

After breast cancer, fibroadenoma is the second most common breast tumour in women and the most common breast lump in women under 30. In India, approximately 10% of women will develop a fibroadenoma at some point in their lifetime. That said, no breast lump should be assessed or dismissed without proper evaluation, because the only way to confirm what a lump is, is through clinical examination and appropriate testing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A fibroadenoma is a non-cancerous growth that forms when glandular tissue (the tissue involved in milk production) and fibrous connective tissue grow together to create a solid lump. It is not a form of cancer and, in the vast majority of cases, does not become cancerous.<\/p>\n

Key characteristics of a fibroadenoma:<\/strong><\/p>\n

    \n
  • Most commonly occurs in women between the ages of 15 and 35<\/li>\n
  • Often feels smooth, firm, and clearly defined with a regular shape<\/li>\n
  • Moves easily under the skin when pressed, which is why it is sometimes described as feeling like a marble<\/li>\n
  • Usually painless, though some women experience mild tenderness around their menstrual cycle<\/li>\n
  • May change slightly in size with hormonal shifts during the menstrual cycle, pregnancy, or when taking hormonal contraceptives<\/li>\n
  • Typically ranges from 1 to 3 cm in size, though larger versions do occur<\/li>\n<\/ul>\n

    Fibroadenomas are strongly influenced by oestrogen, which explains why they are more common during the reproductive years and tend to reduce in size or resolve naturally after menopause.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Symptoms that are more likely to indicate breast cancer than a benign lump:<\/strong><\/p>\n

      \n
    • A lump that grows progressively over weeks, feels fixed to surrounding tissue, and has irregular edges<\/li>\n
    • Skin dimpling or puckering over part of the breast<\/li>\n
    • A change in the texture or colour of the breast skin, including redness or a texture resembling an orange peel<\/li>\n
    • A nipple that turns inward when it was previously normal<\/li>\n
    • Unexplained discharge from one nipple, particularly if blood-tinged<\/li>\n
    • Swelling in the armpit or collarbone area, caused by enlarged lymph nodes<\/li>\n
    • A change in the overall size or shape of one breast without an obvious cause<\/li>\n<\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Because a fibroadenoma and certain early breast cancers can feel similar, clinical assessment alone is not sufficient to distinguish them. A structured diagnostic approach is used.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      • Do not wait to see whether the lump resolves on its own. Any new breast lump should be evaluated by a doctor within two weeks of discovery<\/li>\n
      • Mention how long the lump has been present, whether it has changed in size, and whether it is tender or fixed<\/li>\n
      • Track whether the lump changes around your menstrual cycle, as this can help the doctor understand its likely nature<\/li>\n
      • If you have already been told a lump is a fibroadenoma, continue with follow-up ultrasound as recommended, and return to your doctor promptly if the lump grows, hardens, or new symptoms appear<\/li>\n
      • Women above 30, or those with a family history of breast cancer, should discuss clinical breast examination and mammography as part of their routine health care<\/li>\n<\/ul>\n

        Most breast lumps turn out to be benign, and fibroadenoma is one of the most common and well-understood of these. A clear diagnosis brings relief and eliminates uncertainty. What matters most is not assuming the nature of a lump based on how it feels, but getting it assessed by a specialist who can confirm it with the right tests.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
