Cancer lecture 2, Breast and prostate Flashcards
Who is affected by breast cancer
Both men and women, however it is much more common in women
* 1/8 women develop it
* Second leading cause of cancer death in women (Lung is number one)
Where does breast cancer commonly metastasize
- Bone
- Lung
- Brain
- Liver
Screening recommendations: Breast cancer
- Self breast exam monthly, yearly screening by doctor
- Mammogram, low dose 2d x ray
- Tomosynthesis mammograms: 3d mammogram
- Shows calcifications or masses
- Detects changes in breast
- MRI or ultrasound are used to better assess possible changes in high risk pts
How often should women with average risk be screen for breast cancer
- Ages 40-44: Optional should be screened yearly with mammogram
- Ages 45-54: Should be screened with mammograms every year
- Ages 55+: Every 1-2 years based on choice
How often should women with high risk be screened for breast cancer
- Mammogram+MRI yearly starting at age 30
Women that are at high risk of breast cancer
- BRCA1/2 gene
- 1st degree relative with BRCA 1/2
- Radiation to the chest prior to age 30
Risks to breast cancer
- High genetic risk (BRCA1/2)
- History of prior breast cancer or benign breast disease
- Dense breast
- 65+
- African american or puerto rican descent
- 1st degree relative with breast cancer
- Prior radiation to breast or chest
- Early menarche
- Late menopause
- Nulliparity or 1st child after 30
- Hormone therapy after menopause
- Testicular disorders
- Excessive alc consumption
- Smoking
- Diabetes
- Use of oral contraceptives (Not proven)
Protective factors for breast cancer
- Having children before 30, breastfeeding
- Risk reducing or prophylactic mastectomy (BRCA 1/2)
- Risk reducing ovarian ablation (BRCA 1/2)
S+S breast cancer
- Lumpy or thicking of breast, and axilla
- Change in size or shape of breast
- Dimpling or puckering in the skin of the breast
- Nipple is turned inwards into the breast
- Fluid besides milk from nipple (Especially if its bloody)
- Scaly red or swollen skin on the breast, nippple or areola
- Dimpling in the breast looking like the skin of an orange (Peau d’orange )
Breast Biopsy: Fine needle aspirate (FNA)
Only cells are retrieved
Breast Biopsy: Core needle biopsy
Larger needle, more tissue taken
Breast Biopsy: Image guided biopsy
CT/Ultrasound or MRI to see exact area of abnormality
Breast Biopsy: Sentinel lymph node biopsy (SLNB(
- Assess degree of lymph involvement
- Aids in staging the disease and treatment planning
- The sentinel lymph node is the first lymph node that is close to the primary tumor, where the tumor would drain to
- If the node test positive that could mean the cancer has spread to the lymph and possible other organs
- Radioactive dye is injected near the tumor and is followed externally to see where it drains to
- The lymph node is then excised through a small incision for pathology
What is tested for in a breast biopsy
- Estrogen receptor (ER)
- Progesterone receptor (PR)
- HER2 status
- Tumor type and grade
- Lymph nodes for cancer cells
Informative things such as margins, invasiveness and other features not known until the tumor is removed surgically
SLNB+ LN dissection: Benefits
If negative the surgeon will not have to do more extensive surgery which can lead to more complications
SLNB+LN dissection: Complications
- False negatives
- Infection
- Lymphedema: If like 20-40 are removed the lymph system is interrupted and body cant absorb interstitial fluid, leading to a buildup of fluids
Lymphedema
- Build up of fluid in the interstitial space
- Occurs when multiple lymph nodes are removed or impaired
- Skin becomes thickened, red and tender
- Increased risk of infection
- More lymph nodes removed the worse the lymphedema
- May need to see lymphedema specialist
Breast cancer types: Ductal carcinoma in SITU (DCIS)
- Abnormal cells in the milk duct and have not invaded any tissue
- Early stage, precancerous
When it infiltrates tissue it becomes invasive/infiltrating ductal carcinoma
70-80% of all breast cancers
Breast cancer types: Lobular carcinoma in situ (LCIS)
- Abnormal cells in the milk producing glands and have not invaded tissue
- Early stage, precancerous
When it infiltrates tissue it becomes Invasive lobular carcinoma
More likely to be in both breast
Breast cancer types: Adenocarcinoma
Starts in the breast tissue, not the milk glands or duct
Breast cancer types: Triple negative breast cancers
- ER negative
- PR negative
- and HER2 negative
- Hella aggressive
Breast cancer types:Inflammatory breast cancer
- Aggressive breast appears inflamed, tender, swollen
- May not be evident on mammogram, not presenting as a lump
- Only accounts for 1-5%
Breast cancer surgery: Lumpectomy
- Only removes the lump
- Only removes the tumor and tissue around it +lymph somtimes
- After breast looks normal
- May require post op radiation+chemo, hormonal therapy or targeted drug
- Goal is breast preservation and cure
Breast cancer surgery: Total mastectomy
- Entire breast and SLNB with removal of one or more axillary lymph nodes
- May need chem, radiation and other therapies
Breast cancer surgery: Modified radical mastectomy
- All axillary lymph nodes and breast removed
- May need radiation, chemo and other therapies after
Breast cancer surgery: Reconstructive
- Uses implant or tissue from abdomen
- Can do nipple reconstruction with tattooing
Breast cancer surgery: Nursing interventions
- Elevating HOB 30 degrees post op
- Lie on unaffected side, support surgical side with pillows
- Surgical arm to be placed in sling when ambulating
- Do not give injections, take BP or obtain blood from affected arm/side
- Offer emotional support
- Monitor document surgical drainage, sites
- Educate on prothesis/ bras
Breast cancer surgery: Education
- Elevate extremity on pillow
- Never have affected arm in dependent position (Use sling)
- Perform arm exercises
- Wear non restrictive clothing
- Wear compression if you have lymphedema
- Provide info about support groups
