The world-leading journal dedicated to clinical oncology research
 The LANCET Oncology is an open accessed, peer reviewed journal that
considers articles of all acpects related to the Oncology.
 The LANCET Oncology covers topics like clinical practice, advocate change
in health policy, and tackle issues related to global oncology. Topics included
are not limited to breast cancer but also- endocrine system cancer;
gastrointestinal cancer; genitourinary cancer; gynaecological cancer;
haematological cancer; head and neck cancer; neurooncology; paediatric
oncology; thoracic oncology; sarcoma; skin cancer; epidemiology, cancer
prevention, and cancer control; supportive care; imaging; and health-care
systems.

 The Lancet Oncology publish a range of article types that
encompass all aspects of oncological medicine: Articles, Review,
Policy Review, Personal View, Clinical Picture, Comment,
Correspondence, News, and Perspectives. It also
publish Series and Commissions (typically in partnership with
societies, governments, NGOs, and academic centres) that aim
to shape and drive positive change in clinical practice and health
policy in areas of need in global oncology.

Breast cancer is the commonest cause of cancer death in
women worldwide. Rates vary about five-fold around the
world, but they are increasing in regions that until recently
had low rates of the disease.
Many of the established risk factors are linked to oestrogens.
Risk is increased by early menarche, late menopause, and
obesity in postmenopausal women, and prospective studies
have shown that high concentrations of endogenous oestradiol
are associated with an increase in risk.

 Childbearing reduces risk, with greater protection for early
first birth and a larger number of births; breastfeeding
probably has a protective effect
 Both oral contraceptives and hormonal therapy for
menopause cause a small increase in breast-cancer risk ,
Alcohol increases risk, whereas physical activity is probably
protective. Mutations in certain genes greatly increase
breast cancer risk, but these account for a minority of cases

The introduction is meaningful and is built in existing literature.
The introduction is logically presented with with opening ,body
and termination like need for the study.
The introduction expiains the basic epidemiology of the breast
cancer .

 Studies of the epidemiology of breast cancer have established that hormonal
factors have a key role in the causation of this disease. Factors that increase
exposure to oestrogens increase risk, and studies in postmenopausal women
have shown a direct association between high oestradiol concentrations and
breast-cancer risk. The low rates of breast cancer in some populations are to
a substantial extent to conditions that are not realistic or desirable for more
developed countries – late menarche, young age at first birth, and high parity.
Feasible changes in risk factors, such as obesity, alcohol consumption,
breastfeeding, and physical activity, could yield important reductions in
breast cancer risk. Further progress may come from the identification of new,
modifiable lifestyle (especially dietary) risk factors. Trials such as those of
tamoxifen and other selective oestrogen-receptor modulators may result in
effective methods for the chemoprevention of breast cancer.

 The conclusion is meaningful .
 The conclusion is supported by the result drawn.
