\n
Procedure<\/div>\n
\n Sentinel lymph node biopsy\n <\/div>\n<\/div>\n
\n
Purpose<\/div>\n
\n Assessment of axillary lymph node involvement\n <\/div>\n<\/div>\n
\n
Approach<\/div>\n
\n Selection of axillary treatment based on clinical findings\n <\/div>\n<\/div>\n<\/div>\n

\n Sentinel lymph node biopsy is used to evaluate lymph node involvement in breast cancer.
\n Axillary management is planned to allow accurate staging
\n while avoiding unnecessary surgical intervention where appropriate.\n<\/p>\n

What is sentinel lymph node biopsy<\/h2>\n<\/p><\/div>\n
\n

\n The sentinel lymph node is the first node to which cancer cells are most likely to spread
\n from the primary tumour.
\n The procedure involves identifying and removing this node
\n to assess for metastasis.\n <\/p>\n

\n This allows evaluation of axillary lymph node status
\n with less surgical burden than routine axillary dissection.\n <\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Axillary management<\/h2>\n<\/p><\/div>\n
\n

\n Decisions regarding axillary treatment are based on clinical findings,
\n pathological results, and overall treatment planning.
\n When appropriate, additional axillary dissection may be avoided.\n <\/p>\n

\n This approach aims to balance disease control
\n with preservation of function.\n <\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Clinical basis for decision-making<\/h2>\n<\/p><\/div>\n
\n

\n Current practice is informed by clinical studies showing that,
\n in selected patients, omission of routine axillary dissection
\n does not compromise outcomes.\n <\/p>\n

\n Treatment is selected based on individual clinical conditions
\n and established practice standards.\n <\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Reducing complications<\/h2>\n<\/p><\/div>\n
\n

\n Axillary lymph node dissection may be associated with complications
\n such as lymphedema, shoulder dysfunction, and sensory disturbance.
\n Careful selection of procedure helps reduce these risks.\n <\/p>\n

\n Treatment planning considers both oncological safety
\n and long-term functional outcomes.\n <\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n
\n

Appointment<\/h2>\n<\/p><\/div>\n
\n

\n Appointments are required in principle.
\n A referral letter from another medical institution is recommended but not mandatory.\n <\/p>\n
