Not having kids younger
Genetics
Exercise in protective
1 in 8 women will get breast cancer - (12%) most common !
Outline what types of HRT can lead to more of a risk of breast cancer
Combined hormone replacement therapy (HRT) appears to increase breast cancer risk, more so than oestorgen only HRT.
Interestingly, taking low dose progesterone in isolation of oestrogen does not seem to increase the likelihood of developing breast cancer.
Oestrogen-only HRT does not appear to increase the risk of breast cancer if used for less than 10 years. However oestrogen-only HRT increases endometrial cancer risk and should generally be avoided unless the patient has undergone hysterectomy.
Hormonal contraceptives are UK MEC4 (i.e. contraindicated) in women with active breast cancer = IUD
Name some genes that increase your risk for breast cancer
BRAC - 1 - 80% chance of breast cancer, and 40% of ovarian cancer
BRAC - 2 - Around 60% will develop breast cancer by aged 80
Around 20% will develop ovarian cancer
There are other rarer genetic abnormalities associated with breast cancer (e.g., TP53 and PTEN genes).
between what ages to we screen for breast cancer?
The NHS breast cancer screening program offers a mammogram every 3 years to women aged 50 – 70 years.
Screening aims to detect breast cancer early, which improves outcomes. Roughly 1 in 100 women are diagnosed with breast cancer after going for a mammogram.
What are some downsides to screening
Anxiety and stress
Exposure to radiation, with a very small risk of causing breast cancer
Missing cancer, leading to false reassurance
Unnecessary further tests or treatment where findings would not have otherwise caused harm
What are some signs and symptoms of breast cancer
Lumps that are hard, irregular, painless or fixed in place
Lumps may be tethered to the skin or the chest wall
Nipple retraction
Skin dimpling or oedema (peau d’orange)
Lymphadenopathy, particularly in the axilla
Deformed/change in breast shape
ask if lumps change at all wiht menstraul cycle
Pain is only a symptom if pin point and very localised pain.
Pain that is MSK related can by shown by getting the pt to lie on the other side that is painful, and with breast dropping down ot the side w gravity - that’ll expose the muscles behind the breast which can show the source of the pain
What things are included in an assessment for breast cancer?
Triple assessment
1 is normal, 5 is clearly malignant
2 - benign
3 - indeterminate
4 suspicios of cancer
Clinical score ((from examination) 1-5
imaging score 1-5
Biopsy score 1-5
generalised breast pain in younger women - likely hormone related, general breast pain in older - likely MSK related
What imaging is used in breast cancer investigations?
Ultrasound scans are typically used to assess lumps in younger women (e.g., under 30 years). They are helpful in distinguishing solid lumps (e.g., fibroadenoma or cancer) from cystic (fluid-filled) lumps. - good for dense breast tissue in younger women -
+
Mammograms (xray) are generally more effective in older women. They can pick up calcifications missed by ultrasound. - used in over 40
as women get older, dense glandular tissue gets relapsed by fatty tissue - turns up as black/dark grey on mammogram (galndular tissue is light grey)
Cancer is white
Ultrasounds is more a focused assement, so cant be used for general screening as would take ages
MRI scans may be used:
For screening in women at higher risk of developing breast cancer (e.g., strong family history)
To further assess the size and features of a tumour
How and why is lymph node involvement investigated in breast cancer?
Women diagnosed with breast cancer require an assessment to see if the cancer has spread to the lymph nodes.
Offered an US of lymph nodes - if abnormal, do biopys of abnroaml lymph node, if normla, do SNB
A sentinel node biopsy (SLNB) is a surgical procedure used to determine whether breast cancer has spread to the lymph nodes. It specifically targets the sentinel lymph node, which is the first lymph node to receive drainage from a tumour.
A sentinel node biopsy is minimally invasive compared to other node surgeries, and helps determine the stage of breast cancer by assessing whether it has spread to the lymphatic system
What is a DCIS? Does it require treatment?
Ductal carcinoma in situ (DCIS), is a pre-cancerous or non-invasive cancerous lesion of the breast. (hasnt invaded the basement membrane of the duct - core biopsy useful for this seeing if this the case)
In DCIS, abnormal cells are found in the lining of one or more milk ducts in the breast.
the abnormal cells have not moved out of the mammary duct and into any of the surrounding tissues in the breast - its not yet become an invasive cancer
It does require treatment
What is the treatment options for a ductal carcinoma in situ?
. Treatment primarily involves wide excision and radiotherapy
or mastectomy if the disease is more extensive. Just to complicate matters, 1% of
high grade DCIS will have axillary node metastases from areas of micro-invasion
within the DCIS. It can be a difficult concept to explain to patients, especially those
with widespread disease who need mastectomy, that they need a mastectomy but
they don’t have invasive breast cancer. Below is a mammogram showing a large
area of typical DCIS associated microcalcification. This case would require a
mandatory mastectomy.
Surgery for breast cancer - what are the two options
Breast-conserving surgery (e.g., wide local excision), usually coupled with radiotherapy - reduces risk of recurrence, makes it the same as a mastectomy
Mastectomy (removal of the whole breast), potentially with immediate or delayed breast reconstruction (also add radiotherapy if large tumour or spread to chest wall)
What are the options and what factors can influence Mastectomy vs breast conservation look at page 30 on breast cancer handbook
Needs masectomy if
Large tumour relative to breast size
more than ome cancer
can take up to 20% of breast, as a general rule
if they have inflammatory breast cancer -
breast cancer in different quadrants
Psychological [atinet choice
if they cba for teh radiotherapy needed with breast conserving therapy or cant have radiotherapy
can have breast conserving therapy if the tumour is small compared to the size of the breast
Radiotherapy can scar and shrink breasts
what are some reasons why people cant have radiotherapy, and so wil need a mastecotmy?
- (aka have had previous radiotherapy to the breast, or lymphoma, or unbale to lie flat and still)
a rare genetic TP53 gene - radiotherapy will lead to sarcoma
WHat is inflammatory breast cancer?
waht is the mangaement
red, oedematous, as cancer has invaded the dermal lymphatic system to cause inflammation/oedema
need mastectomy - as need to take over a 1/3 of the skin off the breast
When is axillary clearnace offered in breast cancer treatment?
Removal of the axillary lymph nodes is offered to patients where cancer cells are found in the nodes. Usually, the majority or all lymph nodes are removed from the axilla. This increases the risk of chronic lymphoedema in that arm
Outline what is meant by grading in breast cancer
Grading - 1 to 3. How the tumour looks (not to be confused with Staging x)
Tumour grade varies from grade 1, where the cells are well differentiated with a
low mitotic rate (and look very similar to normal breast glands down the
microscope) to grade 3 where the reverse is true, and the cells look very abnormal
and have many more mutations in the genes. Tumour grade is an important
prognostic marker used to decide about whether a patient should be offered
chemotherapy or not.
Outline what is meant by staging in breast canc er
Stage 0: Also known as carcinoma in situ. Cancer cells are present but have not invaded surrounding tissues. There is no spread beyond the ducts or lobules.
Stage I: Invasive cancer is detected. Tumors are up to 2 cm and have not spread to lymph nodes or other parts of the body.
Stage II: Tumors range from 2 to 5 cm, or there may be lymph node involvement (cancer has spread to nearby nodes) but not to distant sites.
Stage III: Locally advanced cancer. Tumors may be larger than 5 cm and/or have spread extensively to nearby lymph nodes but not to distant organs.
Stage IV: Metastatic breast cancer. Cancer has spread to distant organs, such as the bones, liver, lungs, or brain.
Stage is anatomical!!
Outline what having the osterogen and progresterone recpetor means
The oestrogen receptor is expressed on about 70% of all breast cancers,
It denotes that the cancer is sensitive to oestrogen which stimulates tumour growth and also that anti-oestrogen therapy will help to control the disease.
==> marker of good prognosis because the women can be treated with anti-oestrogens and the cancers
tend to be less biologically aggressive.
The Progesterone receptor is also an indicator of sensitivity to anti-oestrogens (the ER and PgR are linked).
What are some immunophentupes that have a worse prognositc marker
The Her-2 receptor is over expressed in 15% of all breast cancers and is a poor prognostic marker. if this receptor is up regulated, (i.e. there are more copies on the cell surface,)
the growth pathway is up-regulated and the cells behave in a very aggressive manner.
Ki 67.
More recently, a proliferation marker called Ki 67 has entered clinical practice for cases of borderline aggression
Immunophenotypes with a poor prognostic marker (Her -2 and Ki67) - what is the common treatment of them both?
Her-2
Fortunately this can be combated by use of the new drug trastuzumab (Herceptin) which improves the prognosis substantially for this group
of women.
Ki 67
A high score is a poor prognostic marker - Likely that chemotherapy will be needed
What are the two main types of breast cancer?
Invasive Ductal Carcinoma – NST
NST means no special/specific type, where it is not more specifically classified (e.g., medullary or mucinous)
Originate in cells from the breast ducts
80% of invasive breast cancers fall into this category
Invasive Lobular Carcinomas (ILC)
Around 10% of invasive breast cancers
Originate in cells from the breast lobules (the milk-producing glands of the breast.)
ILC tends to grow in a distinctive, non-nodular pattern, often infiltrating surrounding tissues in a single-file formation, making it harder to detect on mammograms.
What are some horomonal therapies for treating breast cancer?
Pre-menopausal women:
1st line therapy is Tamoxifen which is associated with an approximate 30% increase in
survival rate. It is a selective oestrogen receptor modulator (SERM) (It binds to estrogen receptors on breast cells, blocking estrogen’s effects)
In the breast it has an inhibitory effect and causes tumours cells to stop proliferating and die.
Post menopausal Women:
Aromatase Inhibitors, (Exemestane, Letrozole and Anastrozole). These prevent the
peripheral conversion of adrenal androgens to oestrogens by the aromatase enzyme in
fatty tissues.
What are some side effects of Tamoxifen and aromatase inhibitors?
Side effects include : - - - - -
GI disturbance e.g. nausea, vomiting, usually mild
Hormonal disturbances e.g. hot flushes
Headache, rash (occasional)
Visual disturbances
Promotes thromboembolic disease-DVT, PE
Tamoxifen is a risk factor due to its pro-oestrogen effect on the uterus and bones. It does also have an anti-oestrogen effect on the breast., so risk factor for endometiral cancer
Side effects
include:
* Hot flushes
* Joint pain
* Bone density changes
* Vaginal dryness
