Aim: Breast cancer in men is a very rare neoplasm accounting 1% of all breast cancer with an incidence ratio of 1:100 of men to women and about 1% of all malignancies in men. On the basis of the literature review the authors tried to determine the main characteristics of this rare neoplasm in terms of epidemiology, diagnosis, prognosis, treatment and survival.
Methods: The authors report the experience of the Breast Unit of the San Giovanni Addolorata Hospital in Rome, where 4 cases of male breast cancer were observed and treated over 784 breast cancers.
Results: All tumours were ductal carcinomas. The extent of disease was as follows: 3 cases with stage I and 1 case with Stage IIIB; in two cases estrogen and progesterone receptors expression was 100% and in the other two cases it was 20-80%. Median follow up was 57.5 months. At present, after 6-year follow up the three patients with stage I are in good conditions; the patient with stage III died after 27 months with metastatic disease.
Conclusions: Surgical treatment remains the gold standard in male breast cancer. The prognosis for males with breast cancer is similar to female patients on equal terms of stage of disease. Adjuvant therapy is based on retrospective studies of male breast cancer conducted over the past 20 years using the guidelines for breast cancer in women.

Study Objectives: Cancer-related fatigue is one of the most common symptoms in cancer survivors. Cognitive behavioural therapy for insomnia (CBT-I) can improve fatigue, but mechanisms are unclear. This secondary analysis of a randomized controlled trial evaluated whether CBT-I led to a significant improvement in fatigue, accounting for change in comorbid symptoms of insomnia, perceived cognitive impairment (PCI), anxiety, and depression.

The efficacy of photodynamic treatment (PDT) against deep-seated tumor is hindered by low penetration depth of light as well as hypoxic conditions which prevails in tumor. To overcome this limitation, Near-infrared (NIR) absorbing photosensitizers have been investigated actively. In the present study we evaluated the PDT efficacy of an NIR absorbing chlorophyll derivative 'Cycloimide Purpurin-18 (CIPp-18)' in Human Breast carcinoma (MCF-7) and cervical adenocarcinoma (Hela) cells under normoxic and hypoxic conditions.

Purpose Of Review: Male breast cancer (MBC) is a rare entity which often arises in elderly people. Aim of this review is to evaluate the principal issues related to MBC in elderly, because the therapeutic management of disease is not only related to the biological behavior of the tumor, but also to the comorbidities and frailty of older population. A scoping literature review was performed on Pubmed and Cochrane Database using the following keywords: therapeutic management/ male/ breast cancer/ elderly patients.

Background: The standard first-line treatment for human epidermal growth factor receptor 2 (HER2)-positive recurrent/metastatic breast cancer currently includes pertuzumab plus trastuzumab and docetaxel. This study aimed to evaluate the effectiveness of KN026, an anti-HER2 bispecific antibody, plus docetaxel in first-line treatment of HER2-positive recurrent/metastatic breast cancer.
Methods: This open-label, single-arm, phase II study enrolled patients with HER2-positive recurrent/metastatic breast cancer in 19 centers across China from December 30, 2019 to May 27, 2021.
Informed choices for some, but not for others: An exploration of Australian midlife women's participation in mammography screening by social class.

Background: Population-level mammography screening for early detection of breast cancer is a secondary prevention measure well-embedded in developed countries, and the implications for women's health are widely researched. From a public health perspective, efforts have focused on why mammography screening rates remain below the 70% screening rate required for effective population-level screening. From a sociological perspective, debates centre on whether 'informed choice' regarding screening exists for all women and the overemphasis on screening benefits, at the cost of not highlighting the potential harms.
