Axillary dissection is a surgical procedure that incises (opens) the armpit (axilla or axillary) to identify, examine, or remove lymph nodes (small glands, part of the lymphatic system, which filters cellular fluids).
Axillary dissection is utilized to stage breast cancer in order to determine the necessity of further treatment based on cancer cell spread. Additionally, axillary dissection includes removal and pathological examination of axillary lymph nodes for persons having operable
If axillary dissection is not performed, recurrence of cancer in the armpit is common even after breast surgery. Recent evidence suggests that persons who underwent lumpectomy alone without axillary dissection had a 10-year average recurrence rate of 28% in the axilla. Generally, recent evidence also suggests that the more nodes and tissues removed in the axilla, the lower the risk of recurrence of cancer. Research also indicates that 10-year axillary cancer recurrence rates are low (10% for node negative and 3% for node positive) for women who have mastectomy and axillary node removal. The recurrence rate for breast cancer is approximately 17% for women who did not have axillary node removal.
Lymph nodes (or lymph glands) are filtering centers for the lymphatic system (a system of vessels that collects fluids from cells for filtration and reentry into the blood). Additionally, there is a complex arrangement of muscles, tissues, nerves and blood vessels. Axillary dissection is surgically explained in terms of three levels. Level I axillary dissection is also called lower axillary dissection because it is the removal of all tissue below the axillary vein and extending to the side where the axillary vein crosses the tendon of a muscle called the latissimus dorsi. Level II dissection is continuous—it includes the removal of level tissues and further extensive removal of cancerous tissues. Level II dissection removes diseased tissues deeper in the middle (medial) area of another muscle called the pectoralis minor. Level III dissection is the most aggressive breast cancer axillary surgery, and it entails the removal of all nodal tissue (tissues related to the lymphatic system) from the axilla.
Operable breast cancer is the primary indication for axillary dissection. Persons receiving this surgery have been diagnosed with breast cancer and are undergoing surgical removal of the breast. Diagnosis of breast cancer typically involves palpation of a lump (mass), and other tests such as mammography (special type of x ray used to visualize deep into breast tissues) and biopsy. The specific diagnosis to estimate the extent of axillary (cancerous) involvement can be made by performing a sentinel node biopsy. The sentinel node is the first lymph node that drains fluid from the primary tumor site. If there is no presence of cancerous cells in the sentinel node, the likelihood that higher echelon lymph nodes have cancer is very small. Conversely, if cancerous cells are detected in the sentinel node, then axillary dissection is recommended.
Preparation for axillary dissection is the same as that for modified radical mastectomy . This includes but is not limited to preoperative assessments (special tests and blood analysis), patient education, postoperative care , and follow-up consultations with surgeon and cancer specialist (medical hematologist/oncologist). Psychotherapy and/or community-centered support group meetings may also be beneficial to treatment.
One of the major problems that can result from axillary lymph node removal is lymphedema (fluid accumulation in the arm). Postoperative aftercare should include the use of compression garments, pneumatic compression pumps, and massage to combat fluid retention. Additionally, persons may have pain and should discuss this with the attending surgeon. Other surgical measures for aftercare should be followed similar to persons receiving a modified radical mastectomy. Skin care is important and caution should be exercised to avoid cuts, bites, and skin infections in the affected area. Further measures to control lymphedema can include arm exercises and maintenance of normal weight.
There are several direct risks associated with axillary surgery. A recent study indicated that approximately 31% of persons may have numbness and tingling of the hand and 10% develop carpal tunnel syndrome. In females who have had a previous breast surgery before the axillary surgery, recurrent wound infections and progression of lymphedema can occur. Additionally, persons may also feel tightness and heaviness in the arm as a result of lymphedema.
Normal results can include limited but controlled lymphedema and adequate wound healing. Persons receiving axillary dissection due to breast cancer require several weeks of postoperative recovery to regain full strength.
Sickness and/or death are not necessarily related to axillary surgery per se. Rather, breast cancer outcome is related to breast cancer staging. Staging determined by axillary surgery can yield valuable information concerning disease progression. Early stage (stage I) breast cancer usually has a better outcome, whereas advance stage cancer (stage 4) is correlated with a 10-year survival rate.
Currently research does not support other therapies. Further study is required but other therapies are currently not recommended. There are no adequate alternatives to axillary surgery in breast cancer persons. The most recent evidence suggests that removal of lymph nodes and tissues in the armpit is correlated with elevated survival rates.

The procedure is performed in a hospital equipped to perform major surgery. A general surgeon usually performs the operation with specialized formal training in surgical oncology (the specialty of surgery that provides surgical treatment for operable cancers).
How bad will it look after healing?
Any pictures on the web?
Thank you
After a axillar disection form a carcinom in situ, I have a paiful axilla, because I suspect the rib was broken and placed surgically in a specific way.
1. How can I see where the rib was broken?
2. I have a normal position x ray examination, but I don't have the comment of it. Who is able to interpret it?
3. Which is the difference between pleural callus and the callus of the rib? When I did the Pet Ct examination I didn't know about the broken rib.
4. All the tumoral markers are OK.
In my case after a pet CT I discovered "On the scans, at the level of the 5th rib small focal FDG uptake is represented, in the surgical area.".
The conclusion :
" The FDG uptake observed, on the left-sided mastectomy area, raises the suspicion of local recidivation. Control of the region if necessary aspiration can be recommended. In the right shoulder joint degenerative etiology is probable. Otherwise pathological accumulation was not represented. In the left axilla, stadium after operation. In the lung pastiradiation residuum. Pleural callus 1s.."
This was after discoivering melonomia.The operation was some 9 years ago and I have had continual massage to control the discomfort.
However it has got considerable worse with pain starting under both armpits even at rest and when I do any exercise I immediately get a heaviness in my upper right arm which spreads over my chest. The pain is severe and affects my breathing etc.My limbs are sore especially my joints. I still do treatment(masage) but it is not helping
