Active clinical trials for "Breast Neoplasms"

RATIONALE: Collecting samples of fluid using ductal lavage and nipple aspiration from participants at high risk for breast cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This clinical trial is using ductal lavage to collect fluid from women at high risk for breast cancer.

RATIONALE: New diagnostic procedures, such as vibro-acoustography imaging, may be an effective method of finding microcalcifications and lesions in the breast. PURPOSE: This clinical trial is studying how well vibro-acoustography imaging works in finding breast microcalcifications and lesions in women.

RATIONALE: Studying samples of urine in the laboratory from women with breast cancer may help doctors learn whether tamoxifen and aromatase inhibitors alter the metabolism of estrogens. PURPOSE: This clinical trial is studying the effect of tamoxifen or an aromatase inhibitor on estrogen metabolism in women undergoing treatment for newly diagnosed breast cancer.

Airway management in anesthesia is critical to guarantee appropriate treatment of possible respiratory complications and successful operative practice. LMA® is an alternative to tracheal tube in some surgeries like as mastectomy on breast cancer. Given no need using muscular relaxants in mastectomy, the investigators hypothesized that LMA® would be a superior manner in airway management in radical modified mastectomy on breast cancer than the tracheal tube, and the LMA® might produce less influence on patients' circulatory homeostasis, and easier to be placed before operation.

RATIONALE: Health education programs and screening methods, such as clinical breast examination and examination of the cervix, may help reduce the number of women who develop breast cancer and cervical cancer. PURPOSE: This randomized clinical trial is studying the early detection of breast cancer and cervical cancer in women in India.

We hypothesized that subjects with CYP2D6*10 alleles may have a lower steady state levels of endoxifen due to reduced conversion of tamoxifen to endoxifen. Primary objectives: To determine the steady state pharmacokinetics of tamoxifen and its metabolites To test the effects of genetic polymorphisms of CYP2D6 on plasma concentration of tamoxifen and its metabolites in hormone receptor positive women who are taking tamoxifen as adjuvant treatment for breast cancer.

RATIONALE: Gathering information about how patients respond to stress and measuring stress levels in women with newly diagnosed breast cancer may help doctors provide better methods of treatment and on-going care. PURPOSE: This research study is measuring stress in women with newly diagnosed stage I, stage II, or stage III breast cancer or ductal carcinoma in situ of the breast.

Prospective & Retrospective data collection of breast cancer cases from 2000 to present

The purpose of this study was two-fold: (i) to assess whether MBSR favorably influences psychological status, quality of life, stress hormones, and immune status in breast cancer survivors; and (ii) to explore possible mechanisms by which MBSR may favorably influence these outcomes, in particular, through reduction in fear of breast cancer recurrence and associated perceived stress. Both objectives were studied at the critical transition time immediately following completion of surgical, radiation and/or chemotherapy therapy for breast cancer.

RATIONALE: Learning about the reasons for choosing to have, or not to have, breast reconstruction after mastectomy for breast cancer may help doctors understand why black or Latina women may or may not undergo breast reconstruction. PURPOSE: This clinical trial is studying factors affecting decisions about breast reconstruction after mastectomy in black and Latina women.
