Breast cancer: Is grief a risk factor?

Abstract

SUMMARY Cancer is characterized by the disordered growth of cells that have high capacity of invasion to the tissues and organs. One of the types of tumour that has national incidence and high mortality is breast cancer. Studies show that in addition to hereditary factors, lifestyle and environmental factors, there are factors related to emotional distress (mourning), which interfere with the development of breast cancer. Thus, it is necessary to investigate if the experience of mourning can trigger the appearance of the tumour. For this, an integrative review was performed to verify the existence of the relationship between mourning and development of breast cancer, which presented contradictory results. Methodological errors and lack of access to important information, such as alcohol and tobacco use, were pointed out as the main causes of the contradiction found. A possible mechanism involving cortisol release has been proposed, but more research is needed to make it clear whether the association between mourning and breast cancer really exists, and by what path.

Morbidity and healthcare use among mothers of children with cancer: A population‐based study

“…As noted above, one underlying mechanism may be that both children with underlying cancer predisposition syndromes and their mothers may experience inferior outcomes as a result. However, the process of bereavement itself has also been linked to mortality and cancer incidence in broader populations 46–48 . Prolonged grief and attendant psychological symptoms are common among bereaved parents 49 .…”

Species-Level Characterization of the Microbiome in Breast Tissues with Different Malignancy and Hormone-Receptor Statuses Using Nanopore Sequencing

“…Breast cancer has become the most prevalent cancer worldwide and the first leading cause of cancer death in women [ 1 ]. The occurrence of breast cancer can be attributed to a variety of related risk factors, such as age, family history, alcohol consumption, and obesity [ 2 ], but the exact etiology of breast cancer remains undetermined, and the probability of cancer development, treatment effect, and survival still cannot be accurately predicted [ 3 ]. There are additional factors associated with the development of breast cancer waiting to be explored, one of which is the human microbiome.…”

Searching for essential genes and drug discovery in breast cancer and periodontitis via text mining and bioinformatics analysis

“…Breast cancer is the most common malignant tumor in women, accounting for 30% of female cancers in 2020 [ 1 ]. Several factors are known to affect women’s risk of breast cancer, including lifestyle, age, radiation exposure, obesity and so on [ 2 , 3 ]. Besides, recent studies have shown that the human microbiome, including gut microbiome, may be associated with the development of breast cancer [ 4 ].…”
