Ductal Carcinoma In Situ (DCIS) is a noninvasive breast cancer, classified as stage 0. It accounts for about 20-25% of breast cancer cases and remains localized without spreading to other tissues. While conventional medicine considers DCIS a form of cancer, it does not typically metastasize. Detection often occurs through mammograms, which identify calcifications. Alternative diagnostic options include QT Imaging, CTC blood tests, and thermography. Conventional treatments like surgery and radiation may not always be necessary, as many DCIS cases do not progress to invasive cancer. Managing inflammation, supporting gut health, and maintaining a balanced diet can help mitigate risks.
