Cancer of the breast histopathology:-
Presentation Stage:-
Compared to white British women, black British women have
greater rates of grade 3 tumours and lymph
node-positive illness [9]. This could explain why African women experience
a more rapid progression of breast cancer than European women. Different
subtypes of breast cancer have been identified using gene expression analysis.
Luminal Aluminal B, basal-like, HER2+/ER, and unclassified are some of them.
Compared to postmenopausal African-American and non-African-American women,
premenopausal African-American individuals have a significantly greater
incidence of basal-like breast tumours [22]. Six. Presentation stage European
ladies and their African equivalents are staged very differently at the time of
presentation. When a woman in Africa first gets sick, it's usually already
advanced. More than 70% of the patients in a study conducted in East Africa
presented at stage III or IV [5]. More than half of the patients in trials
conducted in Libya and Nigeria were in stages III or IV [17, 18]. Women are
more likely than men to manifest with the disease in its early stages in
Europe, albeit [23]. 39 percent of the patients in a Nigerian research had fun
gating tumours, and 13 percent had clinical signs of systemic metastasis [4].
Breast Cancer Genes (BRCA1 and BRCA2):-
The absence of health care coverage, particularly in
isolated rural regions, and poverty may be the causes of the advanced
presentation in Africa, as most nations do not provide free healthcare.
Contrarily, healthcare is widely available and cost-free throughout most of
Europe. Additionally, there is a lot of public awareness and screening is
accessible in the majority of European nations. 7. Genetics
of breast cancer (BRCA1 and BRCA2) Breast cancer susceptibility genes 1 and
2 (BRCA1 and BRCA2) are tumour suppressor genes, and mutations in these genes
have been linked to a higher risk of breast cancer. It has been established
that these genes raise European women's risk of developing breast cancer.
According to a Swedish study, case patients who had one first-degree relative
with breast cancer or more than one first- or second-degree relatives with the
disease were more likely to have the BRCA mutations than those who did not have
this level of family history (P0.001) [24]. BRCA mutations were also
statistically significantly more prevalent in women with bilateral breast
cancer than in those with unilateral breast cancer (P=0.002) [24]. Even more
research has indicated that BRCA1 mutation carriers likely to have breast
cancer at a younger age than BRCA2 mutation carriers [25]. The idea of a
hereditary predisposition to breast cancer in native African women on the
African continent has, regrettably, not been the subject of extensive research.
Management:-
Many women could undergo breast
conserving surgery because breast cancer is frequently diagnosed early in
Europe (BCT). For instance, in Poland, from 57 percent in 1984 to 81 percent in
2003, more tumours with diameters less than 5 cm were seen [26]. On the other
hand, only 52% of patients in Africa have tumours less than 6 cm [5]. The
majority of women in Africa undergo mastectomy, adjuvant hormonal therapy, or
chemotherapy, similar to how cancer is treated, while many others just receive
palliative care if the tumour is advanced and inoperable.
In areas with historically low incidence of the disease,
breast cancer is on the rise. Comparatively speaking, Africa still has a low
rate of cancer compared to Europe. The majority of this has been attributed to
a protective reproductive history, which includes late menarche, early
menopause, and high parity with prolonged breastfeeding, irregular menses, and
fewer ovulatory cycles [27]. However, it has been noted that African women
typically show earlier and exhibit a more aggressive form of the disease than
their European counterparts. There may be a genetic propensity for this.
However, some research has been done on their counterparts in
African-Americans. Unfortunately, little genetic research has been done on non-immigrant
African women. In a U.S. research, BRCA2 mutations were more common in
African-American patients than BRCA1 mutations in the white cohort [28].
According to the study, compared to only 12% of the white cohort, nearly 50% of
African-American women carried variations of unknown significance [28].
Additionally, Black women in Europe show a pattern of disease more comparable
to African women than to white women in Europe, indicating that genetics may be
more important in this situation. Basal-like breast tumours are more common while
luminal breast tumours are less common. Young African-American women with
breast cancer may have a worse prognosis due to tumours. The ability to do
research on the genetics of breast cancer in African women in diverse parts of
the African continent would be of enormous benefit. Such investigation may even
find out alterations that are currently unknown.
